Side slides are an excellent and fun exercise to tone your inner thigh muscles. They are best done on a smooth surface such as tile or laminate, wearing good work out shoes. Start in a standing position, feet together with toes turned out slightly (Charlie Chaplin type stance). Lunge out to the right side into a half squat, and then lightly drag your left foot over to the right, as you straighten up to starting position.
Repeat the same to the left side. Do 1 to 3 sets of 12 reps, and feel the burn!
