How to Avoid Over-training to Maximize Muscle Growth

Saturday, March 20th, 2010

Almost anyone that’s picked up a set of weights has or will experience symptoms of over-training at one point in there muscle building program. Over-training can lead to serious injury, chronic fatigue, and even muscle loss.

Over-training is very common amongst athletes and particularly bodybuilders, since they figure that training as much as possible is the fastest way to massive muscle gains.

This couldn’t be any further from the truth however…

Training too much, or at too high of an intensity will lead to over-training.

Now this doesn’t mean you don’t have to put plenty of effort in to see some decent results… Whether you are a bodybuilder, athlete, or just someone that wants to add some additional mass to your frame, you need to train hard and be consistent-that’s a given. In order to get the most out of your genetics, you have to progressively overload the muscles by increasing the weight and / or intensity of each weight training workout.

The problem is however, that many of us increase the intensity of our workouts or get insufficient amounts of rest, or even worse, a combination of both. The trick is finding the right balance between workout volume and intensity, and rest and recovery. And that is exactly what I’ll cover in this article.
The Effects of Over-Training on Bodybuilders

First, let’s take a look at some of the effects of over-training and how one can prevent over-training from happening in the first place.

The Effects of Over-training on the Nervous System

Over-training effects both the sympathetic and parasympathetic nervous systems in the following negative ways:

  • Higher resting heart rate
  • Weak appetite
  • High blood pressure
  • Weight loss
  • Trouble sleeping
  • Increased metabolic rate
  • Irritability
  • Early onset of fatigue

If you are experiencing more than one of the symptoms outlined above, you may be in a state of over-training, and should evaluate your routine as soon as possible.

The Effects of Over-training on Hormone Levels

Many studies have indicated that over-training negatively effects the levels of hormones, as well as the hormone response in the body.  Since hormones play such an important role in the muscle building process, this can have a detrimental effect on your training progress.

Over-training has been show to:

  • Decrease testosterone levels
  • Decrease thyroxine levels
  • Increase cortisol levels
The increase in cortisol levels along with the decrease in testosterone levels is a deadly combination, since this leads to protein tissue break down. This will ultimately lead to a loss of muscle tissue.

The Effects of Over-training on the Immune System

perhaps one of the most alarming repercussions of over-training is it’s negative impact on the immune system-you’re bodies first defense against harmful viruses and bacteria.

Over-training can drastically decrease the levels of antibodies and lymphocytes in your body, making you much more susceptible to illness.  Simply put, this means that if you are in a state of over-training, you are much more likely to get sick.  Since you will have to skip workouts while you are sick, your muscle building progress will slow considerably.The Effects of Over-training on the Metabolic System

Here is a list of how over-training can  effect the metabolic system.  These symptoms are the ones that are most commonly discussed, and are ones we can’t ignore:

  • Micro tears in the muscle
  • Chronically depleted glycogen levels
  • Slow, weak muscle contractions
  • Depleted creatine phosphate stores
  • Excessive accumulation of lactic acid
  • Extreme DOMS (delayed onset muscle soreness)
  • Tendon and connective tissue damage

So you must get the point by now… Over-training effects the entire body, and can seriously impact the results of your muscle building program.

Now let’s take a look at the different types of over-training, and what we can do to prevent it.

Is it Worse to Over-Train With Cardio or Weight Training?

Any form of over-training is a bad thing, however, I’ve personally experienced both types of over-training and can honestly say that over-training in the weight room is much worse, and much more prevalent than over-training through cardiovascular training.

Here are some of the reasons why:

  • In order to grow, muscles must fully recover from their last workout, every workout.  If you are over-training and work the muscles before they have fully recovered, you will break down the muscle tissue before it has rebuilt-making it impossible to build muscle!
  • Over-training with weights makes you more susceptible to nervous systems hormone and immune system issues, which all pose serious health risks.
  • It can lead beginners down the wrong path, perhaps wasting money on unnecessary supplements, or even worse, steroids.

I personally believe that only competitive athletes such as swimmers, runners and bikers run a serious risk of reaching a state of cardiovascular over-training, since there are often training for two or more hours daily.

The bottom line is that it is much easier for the average person to over-train while weight training than while cardiovascular training, and I think the effects can be more serious.

How do I Determine if I’m Over-training?

Determining if you’re currently over-training is fairly simple.   If you’re in tune with your body, you can often see the signs of over-training before they get serious.  If you are losing interest in workouts, are having trouble sleeping, and feel weak and irritable, you may be in a state of over-training and should take a week or more off.

If you are experiencing two or more of the symptoms outlined earlier in the article, this should raise a red flag.

Another variable you can use to determine if you are over-training is by tracking the performance of your workouts.

Has your physical performance improved compared to your last workout?

For example, let’s say last workout you were able to perform 8 pull-ups using your body-weight, but were only able to perform 6 pull-ups the following week.  This means that you have not “out done” your previous workout, have not fully recovered, and therefore are likely over-training.  You nave to re-asses your program and make modifications so that you see progress every workout.

How Can I Prevent Over-training?

n order to avoid over-training, you need to take a multi-facited approach.  Determining the correct training volume and intensity, eating the right foods, and getting the right amount of rest and recovery must all be taken in to consideration.  Now let’s take a look at each of those factors in more detail.

Correct Training Volume

Determining the correct training volume can be difficult, especially when you are first starting out.  You have to determine how much weight to lift, how many repetitions and set to perform for every single workout.

You need to use your own judgment in this case, based on your recovery ability and your recovery methods.  Remember that the goal is that you improve every single workout, and if this isn’t happening, you have to decrease the intensity of your workouts.

This is where many people go wrong though.  You begin your workout and realize that you have not fully recovered.  You can either continue to train at a lower intensity than the previous workout, or skip the workout entirely.

As hard as it may be, skipping the workout is the right way to go.  Just turn around and go home!  Your body is telling you that it needs more rest, and you must listen to it!

There is no point in training at a lower intensity, further breaking down the muscle tissue.   By doing this you will increase your risk of injury, and make it harder for your body to fully recovery for your next training session

Proper Nutrition

Your diet plays a huge role in your muscle building program.  It helps regulate hormone levels, provides energy, and provides the raw building blocks that are used to create new tissue.

Here are some dietary recommendations that will limit the chance of over-training:

  • Do not skip breakfast.  This is one of the most important meals of the day.  Skipping breakfast is very catabolic, and can promote muscle loss.
  • Never let yourself get hungry.  If you’re trying to build muscle mass, you have to constantly feed your body quality foods so that it never has the chance catabolize muscle tissue.
  • Unless you are trying to build muscle and lose fat, make sure you have eaten prior to your training session and are not hungry.
  • Have the largest meal of the day within an hour after your workout.  Do this every single workout!
  • Consider taking proven supplements like creatine, and antioxidants to increase performance and fight free radicals.
  • Eat every 2-3 hours to ensure that your body remains in an anabolic state.
  • Keep glycogen levels at full capacity to inhibit muscle tissue breakdown.

Rest & Recovery

Rest and recovery is essential when it comes to avoiding over-training.  Make sure that you get at least 7 hours of sleep each night, and that you are on a consistent schedule.  As for recovery time, it’s important that you have days off between weight training workouts.  Try to have one rest day between weight training workouts, and never train the same muscle groups on consecutive days.

The Best Nutrition and Diet Tips for Athletes

Saturday, January 9th, 2010

As an athlete, you should always be looking for ways to increase energy, strength and performance. Do you know that through the proper nutrition you can increase all of the above?

But what foods should you eat in order to make sure you stay performing at the top of your game?

We’ll take a look at these top 5 tips to ensure your body is given the proper nutrition for athletic enhancement and performance.

1. Eat 5 to 6 Small Meals a Day

This is by far the #1 tip when it comes to proper nutrition for athletes. Imagine your body like a race car. In order for a race car to function properly you need to give it the best gasoline, oil and tires to run the way it is supposed to. Likewise, without proper nutrition, you will not reach your full athletic potential. By eating 5 to 6 small meals a day, you will be able to recover at a faster rate and increase your energy levels!

2. Consume The Right Ratio of Macronutrients

A topic not discussed very often with regards to proper nutrition for athletes is macronutrients. They consist of proteins, carbohydrates and fats. Without them you will not be able to survive. If you consume the correct amount of macronutrients at the right time, you will be well on your way to achieving your set goals, regardless of the sport you are in.

Definitely make sure that you emphasize complex carbs throughout the day and also include some simple carbs before and after the workouts. Finally, lean protein sources in every meal and some fats that are high in Omega 3s should be the sort of foods that make up your diet.

3. Drink Plenty of Clean Water

The ideal amount of water to consume is your body weight multiplied by .66. So, if you weigh 200 pounds, you will require 132 ounces (200 multiplied by .66) of water. If you are not properly hydrated, your athletic performance will be hindered.

Water also helps to cleanse your body and acts as a detox to any harmful substances that may linger around. It keeps you hydrated and cools you off when you are sweating. In addition, water is required for important processes such as fat burning and muscle production.

4. Consume a Post-Workout Recovery Meal

Post-workout meals are important as they help you replenish your glycogen levels. Glycogen (stored carbs) is needed for energy and gets burned up after a workout as they are your main source of energy. As a result, after working out you should consume a meal that is high in protein and carbohydrates (both simple and complex). By doing this, you will allow your body to recover faster and will allow you to be that much better the next time you exercise or perform any physical activity.

5. Take Your Multi Vitamin and Minerals

Vitamins and minerals allow your body to process chemical reactions at an accelerated rate. B-complex vitamins provide a great health benefit as they help to further break down carbohydrates which in terms will give you energy. While you do obtain vitamins and minerals from certain foods you eat, they usually are not enough for those who are involved in physical activities such as exercising and sports.

Top 10 Bicep Workout Mistakes

Tuesday, March 24th, 2009

As a beginner, it’s often difficult to get into weight training and working out. Most beginners (including me when I was a beginner) don’t want to approach the big guys and ask them questions about workouts and what they’re doing. In today’s article we’re going to look at the top 10 bicep workout and bicep exercise mistakes. The aim of this article is to help people who are new to bicep workout and bicep training techniques. This will ensure that bicep workout and exercise beginners build the most muscle in the time they spend in the gym.

Bicep workout mistake #1 – Bad technique

I go on and on about this on eBicep.com that bicep exercise technique is very important to build big biceps. If you cheat during by swinging the weight or not lifting the full range of motion you are only cheating yourself. For details on how to do each bicep exercise correctly, see Vince Delmonte’s bicep exercises section.

Bicep workout mistake #2 – Too many sets!

There have never been a rule that says more sets = bigger biceps. It’s all about quality or training. You are better off doing 15 sets of quality bicep workout exercises than doing 30 sets of poor form rubbish. You need to concentrate on every rep of every set, watch your bicep muscle as you pull the weight up – focus on it. Just remember, a small amount of quality training will build bigger muscles than a large amount of poor quality training.

 

Bicep workout mistake #3 – Overtraining

Overtraining so very common, especially in a competitive environment like bodybuilding. As a general rule for all muscle groups (not just biceps): if the muscles you are about to trainare still sore from your last workout, don’t train them. Simple as that. As you’ll see from my next point, resting is more important than training.

Bicep workout mistake #4 - Not enough rest

To someone new to working out, this just sounds plain stupid. Buy as experienced muscle builders know, rest is a very important part of building your muscles. When you workout your bicep muscles you’re actually breaking and tearing them (that’s why they “pump up”). And when you rest and sleep your muscle grow and repair. Not enough rest = not enough muscle growth. rest up!

Bicep workout mistake #5 – High reps / light weights

One of the most commonly asked questions in muscle building is, “how many reps should I do to build the most muscle?”. There’s is no straight answer to this because there’s so many variables. There is 1 common rule though, heavier weights/less reps = bigger and stronger muscles. So to get the most out of your bicep workout, drop the reps down to 6-8 on your big bicep exercises and do a few extra sets.

Bicep workout mistake #6 – Same old routine

After a few months of doing the same workout, your muscles will get accustomed to the workout and stop growing. This is called a plateau, and every muscle builder hit’s it at some stage. You need to mix up your bicep workouts every 2-3 months. Change days, change exercises, workout your biceps with a different muscle group. Mix it up, you’ll see and feel the difference!

Bicep workout mistake #7 – Pre-exhausted biceps

It’s important when planning your bicep workout that you don’t work any other body parts that use the biceps before your bicep workout. For example, a big mistake I see all the time is training the back then the biceps. This is not good for your biceps because all the back exercises use biceps as a secondary muscle group. So don’t train your back before your biceps, or vice versa. Train your back and biceps on separate days.

Bicep workout mistake #8 – Wrong exercise order

If you have read our bicep workout page you’ll see that we always do our biggest bicep exercises at the beginning of the workout. These are the heaviest weight movers and need the most energy. So stick to your big exercises like bicep curl at the start of your bicep workout and follow with the smaller exercises.


Bicep workout mistake #9 – Not enough rest between sets

You need to make sure you have adequate rest between sets, other you wont be able to left heavy weights, and you will not be able to grow as much muscle. For the bigger bicep sets a longer rest is OK, take what you need and don’t rush it. If your workout is taking to long, split it over a few days.

Bicep workout mistake #10 – Poor eating

You know the saying, “eat big to get big”, well it’s true. In particular you need to eat as much protein as possible and complex carbohydrates. You need to eat small meals, more often. For more information see our food to eat to build muscle article.

Steady State Cardio 5 X More Effective Than High Intensity Interval Training????

Tuesday, January 27th, 2009
By Tom Venuto, NSCA-CPT, CSCS
www.burnthefat.com

Venuto 2

High Intensity Interval Training, or HIIT for short, has been promoted as one of the most effective training methods ever to come down the pike, both for fat loss and for cardiovascular fitness. One of the most popular claims for HIIT is that it burns “9 times more fat” than conventional (steady state) cardio. This figure was extracted from a study performed by Angelo Tremblay at Laval University in 1994. But what if I told you that HIIT has never been proven to be 9 times more effective than regular cardio… What if I told you that the same study actually shows that HIIT is 5 times less effective than steady state cardio??? Read on and see the proof for yourself.

“There are lies, damned lies, and then there are statistics.”

- Mark Twain

In 1994, a study was published in the scientific journal Metabolism by Angelo Tremblay and his team from the Physical Activity Sciences Laboratory at Laval University in Quebec, Canada. Based on the results of this study, you hear personal trainers across the globe claiming that “HIIT burns 9 times more fat than steady state cardio.”

This claim has often been interpreted by the not so scientifically literate public as meaning something like this: If you burned 3 pounds of fat in 15 weeks on steady state cardio, you would now burn 27 pounds of fat in 15 weeks (3 lbs X 9 times better = 27 lbs).

Although it’s usually not stated as such, frankly, I think this is what some trainers want you to believe, because the programs that some trainers promote are based on convincing you of the vast superiority of HIIT and the “uselessness” of low intensity exercise.

Indeed, higher intensity exercise is more effective and time efficient than lower intensity exercise. The question is, how much more effective? There’s no evidence that the “9 times more fat loss” claim is true outside the specific context in which it was mentioned in this study.

In order to get to the bottom of this, you have to read the full text of the research paper and you have to look very closely at the results.

13 men and 14 women age 18 to 32 started the study. They were broken into two groups, a high intensity intermittent training program (HIIT) and a steady state training program which they referred to as endurance training (ET).

The ET group completed a 20 week steady state aerobic training program on a cycle ergometer 4 times a week for 30 minutes, later progressing to 5 times per week for 45 minutes. The initial intensity was 60% of maximal heart rate reserve, later increasing to 85%.

The HIIT group performed 25-30 minutes of continuous exercise at 70% of maximal heart rate reserve and they also progressively added 35 long and short interval training sessions over a period of 15 weeks. Short work intervals started at 10 then 15 bouts of 15 seconds, increasing to 30 seconds. Long intervals started at 5 bouts of 60 seconds, increasing to 90 seconds. Intensity and duration were progressively increased over the 15 week period.

The results: 3 times greater fat loss in the HIIT group

Even though the energy cost of the exercise performed in the ET group was twice as high as the HIIT group, the sum of the skinfolds (which reflects subcutaneous body fat) in the HIIT group was three times lower than the ET group.

So where did the “9 times greater fat loss” claim come from?

Well, there was a difference in energy cost between groups, so in order to show a comparison of fat loss relative to energy cost, Tremblay wrote,

“It appeared reasonable to correct changes in subcutaneous fat for the total cost of training. This was performed by expressing changes in subcutaneous skinfolds per megajoule of energy expended in each program.”

Translation: The subjects did not lose 9 times more body fat, in absolute terms. But hey, 3 times more fat loss? You’ll gladly take that, right?

Well hold on, because there’s more. Did you know that in this oft-quoted study, neither group lost much weight? In fact, if you look at the charts, you can see that the HIIT group lost 0.1 kg (63.9 kg before, 63.8 kg after). Yes, the HIIT group lost a whopping 100 grams of weight in 15 weeks!

The ET group lost 0.5 kilograms (60.6 kg before, 60.1 kg after).

Naturally, lack of weight loss while skinfolds decrease could simply mean that body composition improved (lean mass increased), but I think it’s important to highlight the fact that the research study from which the “9 times more fat” claim was derived did not result in ANY significant weight loss after 15 weeks.

Based on these results, if I wanted to manipulate statistics to promote steady state cardio, I could go around telling people, “Research study says steady state cardio (endurance training) results in 5 times more weight loss than high intensity interval training!” Or the reverse, “Clinical trial proves that high intensity interval training is 5 times less effective than steady state cardio!”

Mind you, THIS IS THE SAME STUDY THAT IS MOST OFTEN QUOTED TO SUPPORT HIIT!

If I said 5 X greater weight loss with steady state, I would be telling the truth, wouldn’t I? (100 grams of weight loss vs 500 grams?) Of course, that would be misleading because the weight loss was hardly significant in either group and because interval training IS highly effective. I’m simply being a little facetious in order to make a point: Be careful with statistics. I have seen statistical manipulation used many times in other contexts to deceive unsuspecting consumers.

For example, advertisements for a popular fat burner claim that use of their supplement resulted in twice as much fat loss, based on scientific research. The claim was true. Of course, in the ad, they forget to tell you that after six months, the control group lost no weight, while the supplement group lost only 1.0 kilo. Whoop de doo! ONE KILO of weight loss after going through a six month supply of this “miracle fat burner!”

But I digress…

Back to the HIIT story – there’s even more to it.

In the ET group, there were some funky skinfold and circumference measurements. ALL of the skinfold measurements in the ET group either stayed the same or went down except the calf measurement, which went up.

The girths and skinfold measurements in the limbs went down in the HIIT group, but there wasn’t much difference between HIIT and ET in the trunk skinfolds. These facts are all very easy to miss. I didn’t even notice it myself until exercise physiologist Christian Finn pointed it out to me. Christian said,

“When you look at the changes in the three skinfold measurements taken from the trunk, there wasn’t that much difference between the steady state group (-6.3mm) and the HIIT group (-8.7 mm). So, much of the difference in subcutaneous fat loss between the groups wasn’t because the HIIT group lost more fat, but because the steady state group actually gained fat around the calf muscles. We shouldn’t discount simple measurement error as an explanation for these rather odd results.”

Christian also pointed out that the two test groups were not evenly matched for body composition at the beginning of the study. At the beginning of the study, the starting body fat based on skinfolds in the HIIT group was nearly 20% higher than the ET group. He concluded:

“So while this study is interesting, weaknesses in the methods used to track changes in body composition mean that we should treat the results and conclusions with some caution.”

One beneficial aspect of HIIT that most trainers forget to mention is that HIIT may actually suppress your appetite, while steady state cardio might increase appetite. In a study such as this, however, that can skew the results. If energy intake were not controlled, then some of the greater fat loss in the HIIT group could be due to lowered caloric intake.

Last but not least, I’d like to highlight the words of the researchers themselves in the conclusion of the paper, which confirms the effectiveness of HIIT, but also helps put it in perspective a bit:

“For a given level of energy expenditure, a high intensity training program induces a greater loss of subcutaneous fat compared with a training program of moderate intensity.”

“It is obvious that high intensity exercise cannot be prescribed for individuals at risk for health problems or for obese people who are not used to exercise. In these cases, the most prudent course remains a low intensity exercise program with a progressive increase in duration and frequency of sessions.”

In conclusion, my intention in writing this article wasn’t to be controversial, to be a smart-alec or to criticize HIIT. To the contrary, additional research has continued to support the efficacy of HIIT for fat loss and fitness, not to mention that it is one of the most time efficient ways to do cardiovascular training.

I have recommended HIIT for years in my program, using a 1:1 long interval approach, which, while only one of many ways to do HIIT, is probably my personal favorite method. However, I also recommend steady state cardio and even low intensity cardio like walking, when it is appropriate.

My intentions for writing this article were four-fold:

1. To encourage you to question where claims come from, especially if they sound too good to be true.
2. To alert you to how advertisers might use research such as this to exaggerate with statistics.
3. To encourage the fitness community to swing the pendulum back to center a bit, by not over-selling the benefits of HIIT beyond what can be supported by the scientific research.
4. To encourage the fitness community, that even as they praise HIIT, not to condemn lower and moderate intensity forms of cardio.

As the original author of the 1994 HIIT study himself pointed out, HIIT is not for everyone, and cardio should be prescribed with progression. Also, mountains of other research has proven that walking (GASP! – low intensity cardio!) has always been one of the most successful exercise methods for overweight men and women.

There is ample evidence which says that obesity may be the result of a very slight daily energy imbalance, which adds up over time. Therefore, even a small amount of casual exercise or activity, if done consistently, and not compensated for with increased food intake, could reverse the obesity trend. HIIT gets the job done fast, but that doesn’t mean low intensity cardio is useless or that you should abandon your walking program, if you have the time and if that is what you enjoy and if that is what’s working for you in your personal situation.

The mechanisms and reasons why HIIT works so well are numerous. It goes way beyond more calories burned during the workout.

Train hard and expect success,
