Instructions
Lay on a mat with your arms flat by your sides, your knees bent, and your feet flat on top of the round side of a Bosu ball.
Push your feet into the Bosu ball and lift your glutes off the ground until your body reaches a fully-bridged position.
Hold this top position for the designated tempo, try to tense your glutes during this time.
Lower your body back down to the starting position to complete the rep.
