1. Glider Side Lunge This exercise works the legs and glutes, but as you slide your leg back to center, your inner thigh does all the work. You need one of those discs like the Valslide, but if you don't have one, just use the lid of a plastic container and do this move on a carpet. Or wear socks and try it on a wood floor. Stand with your feet a few inches apart, with your right foot on the plastic lid. Make a fist with one hand and cup your other hand over it. Keep your hands in front of your chest throughout the exercise to help you stay balanced. Put weight into your left leg, and as you slowly bend your left knee and squat down, slide your right foot out to the side. Then as you slowly straighten your leg, slide the right foot back in. Most of your weight remains in the leg that's not moving. Complete three sets of 10 reps with each leg. 2. Pilates Inner-Thigh Leg Lifts This exercise might remind you of Jane Fonda's workout videos from the '80s, but it's been a staple of the Pilates mat repertoire for decades. Since the knee is straight, you work all the muscles of the inner-thigh group. Lying on your side, lengthen your bottom leg and cross your top leg over it. Rest either your knee or foot on the floor. Prop your head up with your hand, or rest your head on your arm. As you exhale, lift your bottom leg up, and inhale as you lower it back down. Your torso should stay still while you do this. Do 10 reps, then repeat on the other side. 3. Side Lunge to Curtsy If lunges are new to you, don't add dumbbells to this exercise until you are comfortable with the leg positions. Holding a five- to 10-pound weight in your right hand, side lunge to the left, bringing your right hand to your right foot. Lower your butt as much as possible while sinking back into your heels. Keep your toes pointed forward and your left knee bent to no more than 90 degrees. Push off gently with your left foot, and come into a curtsy position with your left leg crossing behind your right as you press your weight overhead. Keep your hips square and your curtsy tight. Both feet should be pointed forward. This completes one rep. Repeat by stepping immediately into a side lunge from the curtsy. Once you have completed 15 reps, switch sides. Do three sets total.
