How to do it

1. Start on all fours with knees hip-width apart and hands under shoulders.
2. Engage your core and keep your back neutral throughout the movement.
3. Lift one leg, keeping the knee bent at 90 degrees, and push the heel toward the ceiling.
4. Squeeze your glutes at the top, then slowly lower the leg back to the starting position.
5. Repeat for the desired number of repetitions before switching legs.
