30-Minute Strength Exercise Demo: Skater Squat

Standing upright in front of a box that’s about 6-12 inches high, with your left foot on the ground, pick your right foot up off the ground to a 90-degree angle in front of you. Drive your hips back to tap your right knee back and down behind you on the box. Extend your arms with a light weight as you lower, keeping your spine straight. Drive with your glutes to lift yourself back up to the starting position. Do 6-8 reps per leg, and then switch legs for a total of 3 sets.
