1. Marching hip raises
Use your glutes to rise into bridge position. Lift one knee up and kick foot toward ceiling. Return to start and repeat with opposite leg. Do 3 sets of 16 to 20 reps.
Perfect your form: Engage core and glutes to keep thighs level with torso. No dipping!
Dial it down: Lower hips to ground between sets.
Amp it up: After kicking foot up, lower to hip level. With leg parallel to floor, hold for 2 to 3 counts.
