10. Dumbbell Side Lunge: Feeling a little sideways? Standing with feet shoulder-width apart and a pair of dumbbells at your side, take a big step to the side with your left foot, pushing your hips back and lowering your body into a deep lunge position. As you come down, move the dumbbells straight down to the floor so that your chest comes over your left knee. Return to starting position and repeat for reps on both sides.
11. Dumbbell Step-Up/Reverse Lunge Combo: Put a little pep in your step up. Stand 6 inches from a bench with a dumbbell in each hand. Place your entire left foot onto the bench as you step up. Drive through the heel on the elevated leg, bringing the right leg up to hip height. Lower back down to start position, and step back with your left foot into a deep lunge. (Be sure to track your right knee over your ankle at a 90-degree angle.) Repeat for reps on both sides.
