Louie Simmons, powerlifting guru and founder of Westside Barbell, has probably been the most influential person in strength training in the last 20 years. Much of Simmons' methodology has been influenced by the work of A.S. Prilepin, a Soviet sports scientist. Prilepin reportedly reviewed the training journals of over 1000 weightlifters in search of the keys to building maximum strength, which he summarized in the following table.
Percent | Reps per Set | Optimal # of Reps | Total Range of Reps |
---|---|---|---|
< 70% | 3-6 | 24 | 18-30 |
70-80% | 3-6 | 18 | 12-24 |
81-90% | 2-4 | 15 | 10-20 |
> 90% | 1-2 | 7 | 4-10 |
Note: This is a strength training table, so it has lower repetitions than normally used for hypertrophy purposes. Remember, Prilepin was summarizing findings of weightlifters, which have very little need for higher repetition work.
One element left out of this table is the time factor. In previous writings, Simmons limits time between sets on dynamic effort days to increase workload, i.e. more work in less time. This makes the training session more efficient. Decreasing rest times in a training session can also enhance hypertrophy.
So, the first thing we can do to promote hypertrophy with Prilepin's table is to set a limit to rest times. The limit, however, should be relative to the other columns on the chart. It might look something like this:
Percent | Reps per Set | Optimal # of Reps | Total Range of Reps | Rest Period Length |
---|---|---|---|---|
< 70% | 3-6 | 24 | 18-30 | 45-75 sec. |
70-80% | 3-6 | 18 | 12-24 | 60-90 sec. |
81-90% | 2-4 | 15 | 10-20 | 75-120 sec. |
> 90% | 1-2 | 7 | 4-10 | 90-180 sec. |
Let's suppose that you bench press 300 lbs. Take 70% of that number, which would be 210 lbs. Since higher reps tend to promote hypertrophy, 4 sets of 6 reps with 210 lbs. and 75 seconds rest between sets would be a logical starting point.
You might then progress in the following way. This approach would mitigate the risk of overtraining, provided overall volume and intensity were kept in check.
On the fifth week, the percentage could be increased and rest periods increased, with the cycle repeated based on rest period manipulation.
However, six repetitions or fewer probably isn't ideal for hypertrophy, so what might Prilepin's chart look like if higher reps are incorporated?
What follows is an extension of his chart, but clearly, it's not something that he'd likely recommend. Prilepin worked with weightlifters and increased reps decreased efficiency on those lifts.
The goal of this hypertrophy training approach is to regulate intensity and bring a rationale to a field that's often nebulous at best. It's not about the "pump" and it's certainly not about training by "feel."
Percent | Reps per Set | Optimal # of Reps | Total Range of Reps | Rest Period Length |
---|---|---|---|---|
< 70% | 6-10 | 32 | 20-40 | 45-75 sec. |
70-80% | 5-8 | 30 | 20-30 | 60-90 sec. |
81-90% | 5-7 | 21 | 15-25 | 75-120 sec. |
> 90% | 1-2 | 7 | 4-10 | 90-180 sec. |
The middle three columns were changed. By increasing the reps, there's a shift to hypertrophy training.
For hypertrophy, the basic idea is that you want to do 'x' amount of work in a particular time with the required repetition ranges and rest periods. You can modify that in a number of ways as long as you don't do too few reps and rest too long.
However, this chart still doesn't fully articulate all that's required for hypertrophy. As Charles Poliquin has noted, repetition speed or time under tension (TUT) needs to be taken into account, too.
The repetition is broken down into four phases: lowering (eccentric), the transition to concentric, raising (concentric), and the transition to eccentric.
A tempo of 4/1/2/1 timing on the shoulder press would mean that four seconds is spent lowering the weight to the upper chest, a one second pause on the upper chest, two seconds raising or pushing the weight away from the body to extension, and a one second pause at the top of the movement before beginning again.
So, TUT should be incorporated into the table if we're going to be efficient.
Percent | Reps per Set | Optimal # of Reps | Total Range of Reps | Rest Period Length | TUT Range |
---|---|---|---|---|---|
< 70% | 6-10 | 32 | 20-40 | 45-75 sec. | 4/1/1/1-3/1/0/1 |
70-80% | 5-8 | 30 | 20-30 | 60-90 sec. | 4/1/0/1-3/1/0/1 |
81-90% | 5-7 | 21 | 15-25 | 75-120 sec. | 4/1/0/1 |
> 90% | 1-2 | 7 | 4-10 | 90-180 sec. | No Recommendations |
The TUT calculation is based on doing between 25 and 45 seconds of work for a set. The lower rep ranges are more dependent upon the top figure of the TUT recommendation, and the higher repetitions are more dependent upon the lower figure.
You'll notice an emphasis on the eccentric number; namely, it's greater than the concentric number. Eccentric training tends to promote hypertrophy. It's also the major source of soreness due to the type of damage it produces in the muscle and surrounding areas.
The TUT amount throws a bit of a monkey wrench into the previous chart. The best rest periods between sets tends to be those that are shorter. With the goal of doing more work in less time, shorter rest periods accomplish that task.
However, when TUT is introduced into the equation, we want to be sure to allow enough recovery to make future sets productive. In doing so, we need to start at the upper end of the rest period range and the lower end of the rep range.
For example, consider a shoulder press. Assume that 200 lbs. is 68% of the max.
The repetitions are increasing, the number of sets slightly decrease, and the TUT slightly decreases but stays within range, as do rest periods as well.
That's a basic example of how the hypertrophy table, fully articulated, could work.
Now let's use all this info to build some muscle! The goal in designing any hypertrophy program should center on training as much as possible but within recovery boundaries. Frequency combined with the principles above will guarantee results as long as overtraining doesn't occur.
Consider the following split:
Rest 2 minutes between exercises. Warm up completely for all exercises before starting.
Exercise | Sets | Reps | Percent | Rest | |
---|---|---|---|---|---|
A | Flat dumbbell bench press | 3 | 6 | 81 | 90 sec. |
B | High incline barbell press | 3 | 6 | 81 | 90 sec. |
C | Low pulley cable rows | 3 | 6 | 81 | 90 sec. |
All sets are done with a 4/1/0/1 tempo.
Exercise | Sets | Reps | Percent | Rest | |
---|---|---|---|---|---|
A | Squats | 4 | 5 | 81 | 120 sec. |
B | Still legged deadlifts | 2 | 6 | 81 | 120 sec. |
C | Underhand close grip pulldowns | 3 | 6 | 81 | 90 sec. |
D | Dips, elbows in | 3 | 6 | 81 | 90 sec. |
All sets are done with a 4/1/0/1 tempo.

B | Front pulldowns to the chest | 4 | 10 | 70 | 75 sec. |
C | Dumbbell curls | 3 | 10 | 70 | 75 sec. |
* Two sets high on the platform and narrow, two sets lower and wider on the platform.
All sets done with a 3/0/2/0 tempo.
While Pripelin's chart was designed primarily for strength gains, it can be tweaked for hypertrophy to serve more mirror-minded trainees that still want to modulate intensity in an organized manner. Overall, this program contains the right amount of volume, intensity, and frequency to be very effective, assuming that nutritional status is up to par.
Bodybuilding, at least as the popular media portrays it, tends to be much more about feeling than reason. The problem with this approach is that feeling is not a reliable guide. Getting a pump sure feels like you're growing, but without a rationale behind it, you really don't know if you are.
Training with a rationally formulated program builds confidence in the trainee, and it works. And above all, confidence in a program is ultimately what decides its success and the progress of the trainee. This program can build that kind of confidence.
