Tone up your glutes with this easy home workout.
Lower into a one-legged squat (same position as in your squat and run). Place weight into your right heel and keep knees side by side.
Lift your left heel off the ground (picture A) and extend leg behind you. Pull leg back into starting position, keeping it off the ground. Hold your last rep up and pulse for 10 more reps.
