Hold one weight in a rack position up by your shoulders, and hold the other with your arms straight.
Step forward with your right foot, lowering your hips until both knees are bent at about a 90-degree angle. Keep your front knee directly above your ankle, and lower your left knee to just above the floor.
Keep the weight in your heels as you push back to the starting position.
Repeat stepping with your left foot this time, completing one rep.
