How to do it

1. Start in a push-up position with your body in a straight line from head to heels.
2. Squeeze your glute and raise one straight leg up behind you until it's level with your torso - no higher - hold for a moment, then lower it back down and raise the other.
3. Your hips are the test: they stay square to the floor and dead level while the leg lifts, so the work lands in your glutes and core instead of your lower back.
