Sumo Squat and Curl
Begin in a squat with your feet wider than shoulder width apart. Place your feet at a 45-degree angle and stay up on your toes so that your heels don't touch the ground. Hold a dumbbell in each hand and start with your arms directly in front of your body. Squat down while staying on your toes and perform a bicep curl. Make sure your knees don't go past your toes. Slowly return to starting position.
