The purpose of this study was to assess the peak GRF associated with regular push-ups, and those performed with flexed knee, feet elevated on a 30.48-cm box, feet elevated on a 60.96-cm box, hands elevated on a 30.48-cm box, and hands elevated on a 60.96-cm box for the purpose of quantifying the loads of these exercises for exercise intensity progression and to allow for the calculation of exercise load and volume in a program. This study also sought to assess if there were gender-based differences in response to these push-up variations and the relationship between subject height and peak GRF.
