The gravitational resistance or load experienced during the push-up is largely determined by body weight and how it is supported on the ground. Because load relates directly to body weight, the vertical ground reaction force brought on by gravitational resistance during a push-up can be expressed as a percentage of body weight (relative load). Gouvali et al. determined that the relative load in a static position when elbows are extended was 66% of body weight during the standard push-up, but only 53% during the modified push-up. Similarly, Suprak et al.observed 69% and 54% body weight in the elbow extended position during the standard and modified push-ups,
respectively. Suprak et al. also reported relative load of 75% and 62% experienced in the elbow flexion position during the standard and modified push-ups, respectively. These studies suggest that the difference between standard and modified push-ups can be related to differences in moment arm and the relative supported body weight. Overall, as much as three quarters of body weight could be supported during a standard push-up and over half the body weight is supported
during the modified push-up performed by men.
