Weight Loss (Cardio Vs Weights)

To KO fat — and keep it off…

Cardio’s edge Calorie for calorie, cardio has a slight advantage. You’ll burn 8 to 10 calories a minute hoisting weights, compared with 10 to 12 calories a minute running or cycling, says Wayne Westcott, Ph.D., director of research at the South Shore YMCA in Quincy, Massachusetts.

Strength’s edge Lifting weights gives you a metabolic spike for an hour after aworkout because your body is trying hard to help your muscles recover. That means you’ll fry an additional 25 percent of the calories you just scorched during your strength session, Westcott says. “So if you burned 200 calories lifting weights, it’s really closer to 250 overall.” And if you lift heavier weights or rest no more than 30 seconds between sets, you can annihilate even more.

And there’s more good news when it comes to iron’s fat-socking power. “For every 3 pounds of muscle you build, you’ll burn an extra 120 calories a day — just vegging — because muscle takes more energy to sustain,” Westcott says. Over the course of a year, that’s about 10 pounds of fat — without even changing your diet. Yes, please.

Cardio’s edge [radio silence] The repetitive nature of cardio puts serious pressure on your joints, ligaments, muscles, tendons — and the cartilage in between. If you’ve got a weak link, you’re screaming to be benched. That is, unless you hit the weight room.

Strength’s edge In a 2006 study in the American Journal of Sports Medicine, researchers found that a balance-training program — think single-leg squats and anything on a wobble board — reduced the risk of ankle sprains in athletes. “Functional strength training teaches your brain to allow muscle contractions that are quick enough to prevent or minimize injuries,” says lead study author Tim McGuine, Ph.D., senior athletic trainer and research coordinator at the University of Wisconsin-Madison. Your best bet: Choose moves that work your core, improve your balance, and force you to bend at multiple joints — so lunges, rows, squats, and presses are all fair game.
