I am not a huge fan of using partial reps, but will use them sparingly with experienced lifters to “through a wrench into their workout”. When I prescribe them they are performed after the client has already reached momentary concentric failure during a set. But, because partial reps place such high demands on the recovery ability of the muscles being worked, I caution against using them more than once every 4 workouts per body part. In reference to this belief, I received an email from an intermediate lifter claiming a study (J Strength Cond Res, 2004, 18(3), 518-521) proved partial reps should be incorporated in his workout instead of full range reps.?

I did a little research, as always, and found the study the gentleman was referencing. This study was conducted over a 10-week period using the bench press as the criterion measurement. Subjects were divided into three groups. Group one trained with full range of motion sets. Group two trained with partial range of motion sets. A partial range of motion was defined as two to five inches from full extension of the elbows. Group three trained with a combination of both partial and full range reps. All groups were pre and post-tested with a full range of motion one rep maximum. No differences were found between the groups. So should we or shouldn’t we use partial reps?

There are several problems I find with this study that are common to many studies trying to illuminate the most efficacious training principles. First, and perhaps most important, inexperienced, recreational subjects were used. Inexperienced subjects can achieve gains in the first few months on just about any program. Second, the length of time the study was conducted was entirely too short. six, eight or, like this study, 10 weeks is just not enough time to show the efficacy of a particular training protocol. And third, the intensity of the exercises or perceived exertion is not mentioned or monitored. Are the subjects going to failure on their sets? Are some subjects pushing themselves harder than others? Are the subjects training in the same manner on exercises other than the bench press? This study like most training studies shows nothing.

The question, “What’s best workout for building strength and muscle?” has been the subject of heated debates for years. My answer is always the same. There is no one workout that is the best. There is no one workout that works for all. However, there are training principles that do apply to everybody.

Anatomically and physiologically we are identical. A bicep is a bicep and has the exact same function from person to person. An aorta is an aorta. Our anatomical structures may have different shapes and sizes, but they all function the same. This holds true for all tissues in our bodies from blood to hormones. If this weren’t true medicine could not exist. How could an anesthesiologist do his job if everybody were different?

Therefore, in order to get bigger, stronger muscles the same stimulus is needed. That stimulus is short, intense training sessions. Why short? Because we have known for centuries the body can either train long or train hard. A perfect example is to compare distance runners to sprinters. Because of the types of training, one is emaciated looking and one is muscular. Remember you can not sprint a mile. Is it difficult to run a mile, yes? But it is essentially impossible to run a mile with 100% intensity.

The other factor one needs to take into consideration for building bigger, stronger muscles is recovery. How much or how often can you train? Or better yet, how much “should” you train? Here is where the differences in genetics lie. Our muscles need the exact same stimulus in order to cause a chain of events that forces them to adapt by making bigger stronger muscles. However, the rate at which we are able to recover from these intense bouts is as different as the shapes and sizes of our bodies.

So what are you to do? If you’re training using the typical muscle building routine, which is 3 or more working sets per exercise and 4 or more sessions a week, and not getting anywhere, change it. First, reduce your sets per exercise by half and only train each body part once a week. If you still don’t make gains or you plateau after a short while, reduce your sets again. Remember, if you’re training with 100% intensity and you’re not making gains, you’re not recovering.

More is only better when it comes to sex and money.

We all recover from exercise at different rates. Many people who recover quickly have reached a high level of success performing a high number of sets. Many who recover slowly have also been very successful performing low numbers of sets. Because everybody is unique in their ability to adapt and recover from different programs, the number of sets needs to be individualized.

A very important component of a training program that should be given consideration is training frequency. How often can, or more importantly, should I train per week? Optimum recovery time between training sessions is essential if one is going to continue to make progress. Training frequency, which is determined by ones recovery ability, is often a forgotten part of most training protocols.

Don’t be so concerned with how many training sessions you can handle per week. Be more concerned about the optimal amount. More is not always better. In fact, when somebody comes to me for advice because they’ve stopped making progress, usually I either reduce the workout volume or add days off. There is no reason to go to the gym if you’re not going to make progress.

Does it make sense to keep doing the same routine if gains are not being made? Isn’t the definition of “crazy”, doing the same thing over and over expecting different results. If your current program is not working, change it. The number one complaint people have is they’re not making progress or their progress has come to a halt. In both cases, the answer is more recovery time. Understanding the fact our bodies have a finite amount of recovery ability should help explain this concept.

The following is Mike Mentzer’s explanation of overtraining and recovery. I’m sure you’ll find it interesting.

In bodybuilding, the idea is to impose a training stress onto the body that will serve to induce the biochemical changes which result in muscular hypertrophy. Applying any more of the training stress (high-intensity) than is required by nature will result in the equivalent of over-dosing on a medicine; or, as we say typically in bodybuilding – overtraining.
A person exposed to the sun’s ultraviolet rays at the equator in summer would not have the slightest concern whether the intensity of the sunlight stress is high enough to disturb the physiology sufficiently to induce an adaptive response, i.e., the buildup of a suntan. His only concern, his overriding consideration, would be to properly regulate the volume (or duration) and frequency of exposure time so as not to overdose on the stress/stimulus; and, thereby, incur a sunburn or, in extreme cases, death. A person seeking to develop a suntan at the equator, or wherever the intensity of the sunlight is high has no concern that he will develop a suntan; but only if he doesn’t overexpose. (Note that bodybuilding science is largely based on the medical discipline of stress physiology. Also, that the end result of the healing of a sunburn is not a suntan, just as the end result of the healing of overtraining is not greater strength or added muscle.)
As the stresses grow progressively greater, they will eventually reach a critical point such that they constitute overtraining. The first symptom will be a slow down in progress; and if the individual continues with the same volume and frequency protocol, the stresses will continue to increase until there is a complete cessation of progress, typically referred to as a “sticking point.” One need not ever experience a slow down in progress, let alone a sticking point, if he bears in mind all the while that as the weights grow progressively greater so do the stresses; and he must do certain specific things to compensate for them.

How often can, or much more importantly, should I train per week? Optimum recovery time between training sessions is essential if one is going to continue to make progress. Training frequency, which is determined by ones recovery ability, is often a forgotten part of most training protocols. It never ceases to amaze me, how many people train for months and years experiencing little or no success, and never consider the fact they maybe doing too much.

You can never train too hard, but you can train too much. Training ?too much? can actually be described in two ways. The first and probably the most common way, is training too often. If you are training with 100% intensity, you should not be able to train a body part any more frequently than once every 6-8 days. Everyone should realize that if you are still feeling it from the previous workout of the same body part, then it is best to take a few more days of rest. I have actually heard people say that they train even if they are sore because it is harder on the muscles. True, it is harder on the muscles, but not in a positive way. Ask yourself, ?Where is the logic in training a muscle before it is recovered?? The muscle hasn?t had a chance to adapt to a previous training session and you tear it down with another. Training may stimulate your muscles to grow, but they don’t grow during training. Proper nutrition and enough rest between sessions is what facilitates recovery and allows the muscles to grow. If you train before the muscle is recovered, you not only slow or put a halt to your progress, you increase your risk of injury.
