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.

Fat Burners: The Unadulterated Truth

Tuesday, January 27th, 2009

By Tom Venuto, NSCA-CPT, CSCS

Fat burner supplements are advertised everywhere these days – on the internet, in magazines and even on TV. The ads almost always feature a very lean fitness model or bodybuilder and claim that these products, usually pills, were the secret to their six pack abs and very low body fat levels. Some of these ads suggest that the only way to get as lean as the “hot bodies” you see in the ads is by taking their “miracle pills” and that proper nutrition and exercise alone is not enough.

While I won’t dismiss the fact that there are ingredients in some fat “burner” products that might help a little bit, I take great displeasure in seeing misleading advertising claims as well as the misleading use of models who are often paid to endorse the product even though they may never have even used it (they’re just models!)

Many “fat burner” companies have been sued by the Federal Trade Commission for false advertising, false claims and falsifying before and after photos.

The best you get is a slight thermogenic effect and possibly some slight appetite suppression. A few products might work through other mechanisms like improving thyroid, but if you forgive me the generalization, I consider the effects of all these “fat burner” products to be minutia.

In one of my previous newsletters, I said that in my opinion, 97% of your results come from nutrition and training and maybe you get an extra 3% advantage from supplements. Just so you know those numbers arent something I just pulled out of thin air, lets take an example:

I have reviewed scientific data that EGCG, the active ingredient in green tea extract, if consumed in enough quantity, could increase thermogenesis / metabolic rate by an average of about 75 calories in 24 hours. Since ephedrine was taken off the market, green tea extract appears in many ephedra-free formulas these days. What is a typical calorie expenditure for an active male in 24 hours? lets say 2700 calories per day. 75/2700 = 2.7%.

That little extra doesnt hurt, especially when it’s delivered in a healthful package such as green tea (rather than central nervous system stimulants), but it’s minutia in the bigger picture. Another way to put this into perspective is to make a list of what other things would burn 75 calories (for 150 lb person:)

  • walk your dog for 15 minutes
  • walk for 5 minutes at normal casual pace three times a day
  • 30 minutes of ironing
  • bagging leaves and grass clippings for 14 minutes
  • re arrange your furniture for 10 minutes
  • wash your car, 15 minutes
  • vacuuming for 15 minutes
  • 7.2 minutes of walking up stairs (could be spread throughout the day)

Ah yes, but why move your body when you can take the pill and metabolism increases while you sit and watch TV? How about for your health? A body that is not moved, rots away. Unlike a car which only has so many miles on it and wears out from over-use, people are the only “machines” on earth that fall apart from under-use.

Here’s what any good personal trainer will always tell you: No amount of calorie restriction or pill-popping will ever give you FITNESS. It willl never give you STRENGTH. it will never get you MUSCULARITY. It will never give you FUNCTIONALITY. At best it will help you reduce body mass slightly.

On one hand, I’m tempted to say that everything counts and that yes, 75 calories here and 75 calories there, it ALL adds up, because it does. After you’re exercising regularly and all your fundamentals are in place, details and little things do matter.

I’m simply asking you to put the benefits of any fat burners in proper perspective and realize that (1) there is no “need” for taking them and (2) the claims made in the ads are often erroneous or exagerrated.

My advice on fat burners:

1. NEVER buy a fat burner unless you get independent verification of the claims made for the product.

How do you KNOW they really work? Are you SERIOUSLY going to take the advertisers word for it? Are you SERIOUSLY going to take someone else’s testimonial as fact? Get verification for yourself by going to the pub med data base and looking for the primary research.

2. Put it in perspective

With those products that work, such as those providing a small thermogenic effect, put that in perspective as compared to how easily you could burn that many calories with even light exercise like walking or housework. Keep in mind the additional fitness and strength benefits you will obtain from exercise as opposed to doing nothing and popping a pill.

3. See if there are any side effects or health warnings.

With all supplements and especially with prohormones or stronger thermogenics like the ephedrine and caffeine stack, (if you still have access to them), understand the risk to benefit ratio, and be certain you know the dangers and contraindications.

4. Read the label and see if the product contains enough active ingredient to even work.

A classic scam is when a “fat burner” advertisement quotes research that a certain ingredient boosts metabolism, which might be true. What they may not tell you is that all the research with positive results used a large dosage of the ingredient, which might not be cheap. So the supplement company includes a “pinch” or “light dusting” of that ingredient just so they can say it’s in the bottle, even though it’s nothing more than “label decoration.” Then they have the audacity to invoke the research studies in their advertisements when the amount of the ingredient in their product is no where near what was used in the research!

5. Proprietary blend scam.

Some companies don’t let you see how much ingredient is in the product formula, because it contains multiple ingredients and they say their formula is a “trade secret” aka “proprietary”, so they list what is in the product but not how much. Well, if you don’t know how much is in there then how are you supposed to know whether it contains the proper dosage? (answer: you don’t!)

6. Make sure there is human research, not just rodent research.

In many cases, advertisements cite studies on rats and mice as “proof” under the assumption that the product will produce the same results in humans. Animal research is an important part of the scientific method, as it is often used to help find areas of research where human study should be pursued, or in the other direction, to trace back the mechanism that makes something work. However, for obesity research in particular, a positive finding in rats does not mean the same thing will happen in humans.

7. Look for more than one human study.

Consider trying a supplement after it has human research that has been replicated by different research groups which are not industry-sponsored. My policy is that I will usually only give a “buy” rating to a supplement when a product has an intitial well-designed human controlled trial published and then similar research has been replicated by another research group that is not supplement-industry funded.

Actually, I think it’s a good thing that nutrition and supplement companies fund and sponsor some of the research. They should. They should not only back up their claims with published clinical trials, they should share some of the cost of this expensive research.

However, a basic principle of the scientific method is replication. Other researchers should be able to duplicate the findings. Therefore, while the funding source does not necessarily prove bias, if there is only one study available on a supplement and it is company or industry sponsored, I usually take it with a grain of salt and put an asterisk next to it while I wait for confirmation from another study. (You might be surprised at how infrequently this type of confirmation occurs).

Do you really need “more” than nutrition and exercise?

Now, when you weigh the fact that even the products with research backing them only help a little, with the fact that many of the ads lie to you about research, exaggerate claims and hide vital information about ingredients, and with the fact that you can do a few more minutes of exercise per day and get the same results for free, how enthusiastic are you about fat burners? Yeah, that’s why I’m not real excited about them either and based on the fact that I use no drugs and no “fat burner” supplements and I compete in bodybuilding – very successfully – I’d say that the assertion, “it takes more than nutrition and exercise to get six pack abs” is patently false.

Train hard and expect success,
