Weighted Lateral Lunge With Knee Drive
Stand with your feet together and hold a dumbbell with both hands at your chest, elbows down. Keeping your chest lifted, take a large step out to the side, push your hips back and bend your right knee so it tracks over your toes while keeping your left leg straight. Push off your right foot, and as your left leg straightens, bend your right knee and lift it in front of you at hip height. Extend your right leg to the side again and repeat. Complete all reps on one side, then switch.
