The push-up and the pull-up are foundational benchmarks of upper body strength, yet they represent fundamentally different types of movement. People often wonder how many repetitions of the more accessible push-up are comparable to a single, challenging pull-up. A direct conversion rate—such as 20 push-ups equaling 1 pull-up—does not exist and is not scientifically valid. This is because the exercises engage different muscle groups, move different amounts of body weight, and rely on opposing biomechanics. Understanding why this conversion is impossible, and how to measure comparative strength instead, offers a more meaningful path toward balanced fitness goals.
The Fundamental Difference in Muscle Engagement
The lack of a conversion ratio lies in the antagonistic nature of the movements, meaning they work opposing muscle groups. The push-up is a horizontal pushing exercise, primarily activating the muscles responsible for pressing away from the body. These pushing muscles include the pectorals (chest), the anterior deltoids (front of the shoulders), and the triceps (back of the arms).
Conversely, the pull-up is a vertical pulling exercise, requiring the use of muscles that draw the body toward an object. The main muscle groups activated are the latissimus dorsi (lats), the biceps, and the rhomboids (upper back). Strength developed in the anterior muscles used for pushing does not directly translate into equivalent strength for the posterior muscles used for pulling.
This physiological separation means an individual may possess high endurance in their pushing muscles but have very little maximum strength in their pulling muscles. The two movements are complementary, not interchangeable, and both are necessary for well-rounded upper body development. Focusing exclusively on one movement pattern can lead to muscular imbalances and potential postural issues.
Factors Determining Exercise Difficulty
Beyond the difference in muscle groups, the biomechanical difficulty of the two exercises is unequal due to the amount of body weight moved. A standard pull-up requires lifting nearly the entire mass of the body against gravity. Since only the hands and forearms remain fixed on the bar, a pull-up involves lifting approximately 90% to 95% of total body weight.
The push-up, by contrast, is performed horizontally, allowing the feet to support a significant portion of the body’s mass. Research indicates that a traditional push-up involves lifting only a fraction of the total body weight, typically ranging from 60% to 75%. This difference in resistance load is substantial, making the pull-up inherently a heavier strength exercise.
Individual body geometry also introduces variables that defy a fixed conversion rate. For example, a person with longer arms will experience different leverage during a push-up compared to a person with shorter arms, even if their body weights are identical. This variability makes any attempt to create a universal conversion ratio impossible.
Establishing Your Relative Strength Levels
Since a direct numerical conversion is not possible, a better approach is to assess and balance relative strength levels between the two opposing movement patterns. Fitness professionals recommend comparing the maximum force an individual can generate in a push movement with the maximum force in a pull movement. This comparison is a practical metric for creating a balanced training program.
One method involves setting a Repetition Maximum (RM) for a weighted or assisted pull-up that matches the body weight moved during a push-up. For example, if a person weighs 180 pounds and lifts 65% of that weight in a push-up (117 pounds), they can use an assisted pull-up machine to achieve a net pull load of 117 pounds. The number of repetitions achieved at that standardized load can then be directly compared to the maximum push-ups performed.
Studies show that pushing strength can be significantly greater than pulling strength, sometimes by a ratio of 1.5-to-1 or more. The goal in a balanced training program is to minimize this discrepancy. A simple way to track this is to incorporate both bodyweight push-ups and inverted rows, a horizontal pulling exercise, and aim for a similar repetition capacity for both.
Achieving a balanced ratio between pushing and pulling capacity is a superior training goal to seeking an arbitrary numerical conversion. This focus supports joint health and enhances overall functional strength. By utilizing metrics like the repetition maximum at a standardized load, trainees can effectively measure their progress in both planes of motion.
