I have to admit that I'm a skeptic when it comes to any exercise that promises rapid change. However, while I haven't done this move that promises thinner thighs in three weeks for the full three weeks, I can promise that it works all the right muscles.

• Stand with your feet slightly wider than shoulder-width. If you have a body bar, great -- hold it across your shoulders with a wide grip. I don't have a body bar, so I held five pounds weights in each hand (with my hands held at my sides).
• Bend your left knee and squat down on your left side, keeping your right leg straight until you feel a stretch in your right inner thigh.
• Tighten your butt and push up with your left thigh muscle until you reach a standing position.
• Repeat with your right leg. Do 10 reps on each side.
