Fire Hydrant

How to do it

1. Start on all fours with your hands under your shoulders and knees under your hips.

2. Brace your midsection so your lower back does not sag, and keep it braced.

3. Keeping your knee bent, lift one leg out to the side until your thigh is roughly parallel with the floor.

4. Keep your shoulders and hips square to the floor. Rotating your torso to get the leg higher takes the work off the hip.

5. Lower under control and repeat, then swap sides.
