Thigh Blasters: One Month to Toned Legs

Many women hate their upper legs so much that they don't even try to firm them. Mistake. "Many of your major thigh muscles — your hamstrings and quadriceps as well as your butt — are actually easy to tone," says Evelyn Nunlee, a New York City personal trainer for 15 years. (Inner thighs are trickier, she concedes; to target that trouble spot, add crunches and other lower-abdominal exercises, because your stomach muscles are close to those of your inner thighs.) For quickest results, do Nunlee's four-part thigh routine as well as some form of aerobic exercise three times a week. "Walking, swimming, and biking will give your upper legs definition," she says. "And in-line skating is particularly good. Women who skate have great thighs."

2. Take a big step forward with your left leg until your left thigh is parallel to floor. Do not allow your knee to extend in front of your toes. Let your back leg bend and heel come off the floor. Do not lean forward. Push off the left leg, and step back into starting position. Repeat with right leg. Start with eight repetitions on each leg; work up to 20.
