The purpose of this study was to use Surface electromyography (SEMG) to evaluate the peak and overall muscle activation differences between the muscles involved when a push up is performed under presumably different levels of stability. The three stability levels included a ground pushup, one performed on a BOSU brand stability ball, and one performed with hands suspended by the TRX suspension system. Pairs of pre-gelled Ag/AgCl electrodes were placed on the following muscles along the right side of the body of 20 male college aged Indiana University of Pennsylvania students: Pectoralis Major, Triceps Brachii, Anterior Deltoid, and Rectus Abdominus. Paired sample tests revealed that in all conditions the TRX exhibited higher activation levels than the traditional pushup, with 91.6% of measurements statistically significant at (p
