Place a BOSU ball on the floor with the dome side down and grip the flat edges with your hands about shoulder-width apart. Extend your legs behind you into a plank position with your body in a straight line. Lower your chest toward the BOSU by bending your elbows while keeping your core braced and back neutral. Press back up by straightening your arms, maintaining balance on the unstable surface throughout the movement.
Log your push up bosu ball sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
