6. Hip Raises
Lie face-up on your mat with your arms straight out to your sides, palms up. Then:
(A) bend your knees and place your feet flat on the floor.
(B) lift your hips so that you form a straight line from your knees to your chest. Squeeze your glutes (butt muscles) and hold for a couple of seconds, then return to the starting position (that’s 1 rep).
Do 3 sets of 20 reps, resting one minute between sets.
