Effective Leg Workout: Program for Girls by Jan Jewell

Don't hide your legs in shapeless sweatpants during winter – leggings, skinny jeans, and even swimsuits for vacation let you show off your figure all year round. Use the colder months to get your lower body in peak condition. Jennifer Jewell's program combines leg strength exercises with cardio: the strength component builds muscle, while aerobics boosts metabolism and burns fat. The result is great glutes, quads, and hamstrings. In the first superset, perform 4 sets with 30-second rests between exercises. Do all remaining supersets the same way.
