10 Quick Ways to Go from Fat to Firm

Stay Healthy: Avoid Injuries!

9. Be an expert strength trainer. Slow down and hold the exercise for one count at the peak point of contraction. "Most people move too quickly, so they end up using momentum more than muscle, which compromises performance and can lead to injury," says Los Angeles-based trainer Christel Smith. "Pause for a second, contract the muscle, then slowly lower the weight."

10. Move through soreness. Unless it's severe, stretch or walk often when you're in the midst of post-exercise aches and pains. "The worst thing you can do when you're sore is be a slug and lie on the couch," says Brad Schoenfeld, author of Sculpting Her Body Perfect. The more active you are, the more nutrients your blood delivers to your muscles, promoting a faster recovery.
