Reps: 15 on each leg
How to do it: Lie on your right side, propping your body up on your right elbow, with knees bent and hips stacked. Place the dumbbell over your left thigh with your left hand.
Lift your right hip up off the floor and turn open your left knee to the ceiling, keeping your feet together. Lower your right hip and lightly tap the ground before pressing back up.
Form tip: Keep your abs braced in tight during the move and press up from your bottom side (not your arm) during the bridge.
