Many coaches have achieved impressive results using percentage-based training methods, and they see no reason to deviate from this approach. This is completely understandable – if the method works for you, then stick with it. However, I’d like to make the argument that a repetition-based training system may be a more effective and practical approach to training design without the need for a calculator or Excel spreadsheet.
To support my point, let’s dive into the pros and cons of percentage-based systems and then explore the advantages of repetition-based systems.
Understanding the Numbers
My understanding of the Percentage System began over fifty years ago thanks to my coach, Jim Schmitz, who was a three-time Olympic coach. At the time, the term “intensity cycle” was commonly used to describe these workouts. Later, I was introduced to the vast body of work on the percentage system through Russian literature translated by Dr. Michael Yessis and sports scientist Bud Charniga.
The most frequently cited article on the percentage system by U.S. sports scientists was written by Alexander S. Medvedyev, whose staging model is frequently cited in NSCA publications. However, I have found the articles by Arkady N. Vorobyev and Robert A. Roman to be particularly accessible and practical.
For newcomers to the sport of weightlifting, I highly recommend Bob Takano’s Weightlifting Training: a Guide for Successful Coaches.Takano is not only a successful coach, but physically practices the principles he teaches. His book is a comprehensive guide to the Russian Percentage System.
Also, consider adding Super Training by Professor Yuri Verkhoshansky and Dr. Mel Siv to your bookshelf. This exercise science textbook provides a broad perspective on the Russian training system. While it may not be the easiest book to read, it is certainly a classic that every strength coach should own.
Strength Factors
In the percentage system, “strength” refers to the maximum amount of weight (1RM) that can be lifted in one repetition. For example, if you bench press 100 pounds in one repetition, then the intensity is 100%. Therefore, 95 pounds corresponds to 95% intensity, 90 pounds corresponds to 90%, and so on.
While bench pressing 80 pounds for 10 reps is more challenging than pushing 85 pounds at a time, 85 pounds implies a higher level of intensity from a training program design perspective.
When muscle magazines describe training intensity as workout difficulty, they usually include a photo of a muscular bodybuilder working out as hard as he can in a leg extension or flexion exercise, which is often misleading. It’s true that bench pressing 80 pounds ten times may seem like more effort than bench pressing 85 pounds once, but from a training program design perspective, 85 pounds implies a higher level of intensity.
In the Russian training system, the intensity level of a workout determines other loading parameters, including the number of repetitions, sets, and total load. Let’s take a closer look at these factors.
Number of repetitions
Intensity percentage is related to the number of repetitions. A common conversion is that one repetition equals a 2.5% decrease from 100%. Most percentage charts tend to skip one repetition, meaning two repetitions equals 95%, not 97.5%. So if you can lift 100 pounds once, then three times should lift about 92.5 pounds and ten times should lift 75 pounds.
Sets.
Intensity level also affects the number of sets an athlete should complete. There is an inverse relationship between intensity and sets; the higher the intensity, the fewer sets completed.

When the intensity of the activity reaches 95%, Zera may suggest 2-3 sets; when the intensity reaches 90%, the prescription may be 4-5 sets. This pattern continues similarly.
Volume is the total workload, and in weightlifting, volume is the accumulation of repetitions. For example, 3 sets of 10 repetitions (30 repetitions) is a greater training volume than 5 sets of 5 repetitions (25 repetitions). Generally, athletes at higher levels can withstand more sets at higher intensities. The percentage distribution of the deadlift for different levels of athletes in a month might look like the following:
Low level athletes
- 70%-75% x 20 sets
- 80%-85% x 10 sets
- 90%-95% x 5 sets
- 100% x 2 sets
High level athletes
- 70%-75% x 15 sets
- 80%-85% x 12 sets
- 90%-95% x 9 sets
- 100% x 5 sets
Below is a sample four-week percentage training program that includes exercises such as front squats, hex bar hard pulls, and incline bench presses, demonstrating the heaviest weekly sets:
Each workout for a weightlifter might include the following, including warm-up exercises:
Day 1
- Snatch: 70 x 2 x 3, 75 x 3, 80 x 3, 85 x 3 x 3
- Jerk: 70 x 2 x 3, 75 x 3, 80 x 3, 85 x 3 x 2
- Deep Squat: 50 x 5, 70 x 5, 80 x 3, 85 x 2 x 4
To simplify the process, especially when dealing with large groups of athletes, software such as Excel can automatically convert percentages to specific weights. Many commercial products also offer these conversions. However, some strength coaches prefer to give athletes percentages and let them calculate the weights themselves, except perhaps for athletes from Ivy League schools, who may be able to figure out these weights in their heads!
One of the big challenges with the percentage system is that the maximum weight for each workout is unpredictable. One solution is to use intensity intervals instead of fixed percentages. Let’s dive into this concept.
The Intensity Interval Solution
The weightlifting textbook written by Russian coach M.S. Okunyev and translated by Charniga contains an article that introduces the concept of training intensity ranges.Okunyev proposes a range of intensities instead of a fixed work intensity. For example, rather than prescribing 80% x 3 x 5, an intensity range of 80%-85% x 3 x 5 could be used. A squat workout might look like the following:
- Squat: 50% x 5, 65% x 5, 75% x 5, 80%-85% x 3 x 5
Here are a few permutations of the three work sets:
- 80 x 5, 5, 5
- 80 x 5, 80 x 5, 82.5 x 5
- 80 x 5, 82.5 x 5, 82.5 x 5
- 80 x 5, 82.5 x 5, 85 x 5
- 80 x 5, 85 x 5, 85 x 5
- 82.5 x 5, 85 x 5, 85 x 5
- 85 x 5, 5, 5
The system provides the flexibility to reduce weight in subsequent sets if the repetition target is not met. Examples:
- 80 x 5, 85 x 3, 80 x 5
- 80 x 5, 82.5 x 4, 80 x 5
- 85 x 3, 80 x 5, 82.5 x 5
The intensity of subsequent sets depends on the success of the previous set. If form is poor, use lighter weights. Feeling in good shape? Then use heavier weights and push the limits!
While using percentages is considered the scientific method of designing workouts and is the best way to train a lifter, it has its drawbacks.
The Percentage Dilemma
The percentage system may look appealing on paper, putting a scientific spin on the strength coach’s approach, but there may be better options. Several factors, including muscle fiber composition, can affect the effectiveness of percentage-based workouts.
Muscle fibers are classified as Type I (slow contraction) and Type II (fast contraction), which are key indicators of muscle strength and endurance capacity. However, there is an inverse relationship between strength and endurance: the stronger the muscle, the worse the endurance usually is. This dynamic relationship complicates the use of percentage conversion charts.
For example, an extreme example would be the quadriceps (primarily a slow muscle) and the hamstrings (primarily a fast muscle). When an athlete uses 90% of their one-repetition maximum load (1RM), they may be able to complete five reps of a leg curl exercise, but only 20 reps of a leg press. The recommended weight for the leg push exercise may be too heavy for the leg curl exercise if traditional percentage conversion charts are used.
Gender Differences: Many strength coaches have found that female athletes tend to be able to complete more repetitions at a given percentage compared to male athletes. For example, a male athlete completes 4 repetitions at 90% of 1RM in the bench press, while a female athlete may complete twice as many repetitions. Therefore, a conversion chart that works for a male athlete may be too light a weight for a female athlete.
Age of Training: As athletes progress through strength training, their neurological efficiency increases, which usually results in fewer repetitions at a given percentage. More experienced athletes can handle more frequent training and higher training percentages.
TRAINING SPECIFICITY: Whether it’s weightlifting training or sport-specific training, engaging in muscular endurance training can significantly change percentage conversions. Strength coach Charles R. Poliquin found that elite rowers can complete 12 repetitions at 97% of their maximum load, while the average person may only be able to complete 1-2 repetitions. Therefore, percentage charts should not be considered absolute values for any single athlete.
Poliquin also noted that this phenomenon exists with the Canadian National Synchronized Swimming Team. These athletes need to perform high speed maneuvers continuously to stay afloat. He found that athletes who could bench press 135 pounds 20 times couldn’t even lift 145 pounds.
Daily Variation: everyone experiences fluctuations in performance. The prescribed weight may be too light in good form and too heavy in bad form.
Training Program: The timing of a workout can greatly affect weightlifting ability. If an athlete is accustomed to working out in the morning, the performance of an evening workout may be very different. For this reason, athletes usually adjust their training program to the time zone in which the competition is taking place. For example, if an athlete typically trains in the morning, but a competition is scheduled in the evening, they should train in the evening as the competition approaches.
WORKOUT SELECTION: Percentage charts are intended as general guidelines only and do not apply to all workouts. For example, achieving high repetitions in the jerk requires a significantly lower percentage, while it’s much easier to accomplish higher repetitions in the dumbbell bicep curl than in the deep squat.
Moving forward: instead of relying solely on intensity percentages, consider letting the number of repetitions determine the load.
Looking back, before the era of personal trainers, gyms were populated with weightlifters, lifters, bodybuilders, and fitness enthusiasts all striving to build muscle and lose fat.In 1972, I became a member of a gym called Zera, which had a vibrant and diverse atmosphere that fostered a strength and fitness community.

Optimizing Weight Training with Zera
The importance of velocity training (VBT) comes to the fore when athletes lift a barbell quickly, with the speed of the repetitions and movements determining the appropriate load.
Determining the optimal weight
Finding the right weight is not complicated. Consider athletes like Laura, a sprinter who recently graduated from Harvard, and Maeve, a volleyball player with a degree in basic education from Fairfield University. In order to prevent training from stagnating, it is crucial to modify your training regimen every few weeks. After identifying the strength qualities to focus on, it’s best to stick with a single repetition program for a few weeks before transitioning to another. Below is a suggested progression program:
- Weeks 1-2: 8/6/4
- Weeks 3-4: 10/8/6
- Weeks 5-6: 8/6/4
- Weeks 7-8: 6/4/2
- Weeks 9-10: 8/6/4
While some have criticized this method for having only one set of challenging movements per exercise, it is sufficient for beginners. Advanced athletes can increase the number of sets to, for example, 12/10/9/8 or 6/4/3/2. To ensure that the body adapts effectively to the target strength mass, it is recommended that repetitions are kept to four (e.g., 12-8, 11-7, 10-6, etc.).
Coping with an Overload Training Program
It is important to recognize that many high school weight training programs are challenged by large class sizes. If a class has over 70 students and only one coach, a simple training program like 8/6/4 may be beneficial.
Engaging Athletes in Workout Cards
One effective strategy is to use workout cards based on a repetition system that athletes can fill out themselves. During my tenure as editor of Zera magazine, I wrote about set/repeat workout cards, which were widely adopted by athletes and physical education students. While software solutions exist, many coaches prefer workout cards because they actively engage athletes in the training process and allow them to track their own personal records.
For an in-depth look at how to implement a repetition program, I recommend reading the foundational books by renowned strength coaches Ian King and Charles R. Poliquin. Two must-read books to start the journey are How to Write a Strength Training Program: a Practical Guide by King and The Poliquin Principles by Poliquin.
Tackling High School Training Challenges
Those responsible for high school weight training usually have to juggle a large number of students at once and may lack extensive experience in workout design. Repetitive workouts can enhance the training experience for students.
The Role of Technology in Strength Training
While technology has provided valuable tools for strength training, especially percentage-based training systems for weightlifters, sometimes it’s best to put down the smartphone and go with the traditional method of letting the athlete determine the load.
