How to do it

1. Lie on your back with your knees bent, feet flat on the floor hip-width apart and close enough that your fingertips can brush your heels, arms resting by your sides.
2. Drive through your heels and lift your hips until your body forms a straight line from shoulders to knees, squeezing your glutes hard at the top.
3. Lower back down with control until your hips hover just above the floor, then lift again.
