Lunges work your entire lower body from your lower legs to your glutes. You can modify the move by stepping backwards into a lunge, taking some of the pressure of your knees.
- Start in a standing position with your right foot in front of your left.
- Make sure your knees and hips are facing forward.
- Keeping your shoulders back and your stomach tight, bend your knees as you lower your body down towards the ground.
- Stop before your left knee hits the floor, and return to starting position.
- Repeat for 10-15 repetitions, then switch sides.
