Pistol Squat
Step 1: Stand in front of a bench or box that’s perfectly at knee height and face away from it while holding one dumbbell with both hands in front of your chest. Also known as the single-leg squat, this unique leg strengthening exercise is a great test of strength and flexibility, and is excellent in strengthening both these areas in your legs.
Step 2: Extend your right leg out in front of you with your toes up and heel a few inches off the floor.
Step 3: Push your hips back and lower your butt onto the bench while keeping your chest up. Revert to your original stance without letting your foot touch the floor.
