What do I do about bands slipping during the chest press and tricep press?
First, make sure you’re getting into the right position for the X3 chest press and tricep press. In order to get the full benefit of the X3 workouts, constant tension must be kept throughout the movement. This will help you reach full fatigue, as well as keep the bands in place. Also keep your shoulders back.
It is easy to let your shoulder move forward and round a bit, which makes it easier for the band to slip up. This will help you focus the workout on the proper muscles.
