Before beginning your exercise routing keep in mind that a healthy diet and some fat and calorie burning exercises are needed in order for the toning exercises to be effective.
One of the most common exercises for toning legs is the lunge which works most of the muscles of your legs. First stand with your feet shoulder-width apart. Take a giant step forward with your right foot. Place your hands on your hips in order to keep yourself balanced. Lower your body straight down. At the bottom of your movement your back leg should form a right angle at the knee. Using only the muscles in your legs, raise yourself back up. This exercise is recommended to be repeated for 3 sets of 30 reps for each leg.
An exercise known as plies works the inner and outer thighs and does not place a lot of stress on your joints. This exercise can be done as moderate or intense as you need. Your feet should be slightly farther apart then shoulder width. Take a small step sideways away from your body with each foot. Turn your feet outward. For support and balance grip the back of a chair or place your hands on your hips. Keep your back straight and lower yourself straight down about six inches and raise yourself back up slowly. If holding onto the back of a chair, do not use the chair to pull yourself back up. Reapeat for 3 sets of 30 reps. For a more intense workout lower yourself farther. For a less intense workout lower yourself less. You can also change the intensity by placing your feet further apart or closer together.
Heel raises work your calves. Stand with your feet slightly farther apart then shoulder width. You may put your hands on your hips if you need help keeping your balance. Raise your body onto your tiptoes and hold for a few seconds then slowly lower back down. Repeat for 3 sets of 40 reps. For increased intensity you can stand on a chair or other sturdy surface such as a step with your heels hanging off the surface and do the exercise that way.
Squats work the upper thighs as well as working the buttocks. Feet should be shoulder-width apart and arms should be hanging at your sides. Be sure to keep your posture straight and upright for this exercise. Lower your buttocks several inches as though sitting in a chair then slowly raise yourself back up into a standing position. This is a somewhat difficult exercise. 3 sets of only 20 reps is recommended.
