1b) Glute Bridge
Sets: 3 Reps: 10
Lie on your back on the floor with your feet close to your butt. Extend your hips by driving your heels into the floor. Raise your butt up without arching your lower back and concentrate on feeling the contraction in your glutes, not your hamstrings. Afterward, rest until you're sure you feel recovered before returning to the deadlift.
