Why you shouldn’t live another day without lifting:
You’ll Lose 40 Percent More Fat
This might be the biggest secret in fat loss. While you’ve no doubt been told that aerobic exercise is the key to losing your gut, weight training is far more valuable. Case in point: Penn State University researchers put overweight people on a reduced- calorie diet and divided them into three groups. One group didn’t exercise, another performed aerobic exercise three days a week, and a third did both aerobic exercise and weight training three days a week.
Each of the groups lost nearly the same amount of weight — around 21 pounds. But the lifters shed about six more pounds of fat than did those who didn’t pump iron. Why? Because the lifters’ weight loss was almost pure fat, while the other two groups lost just 15 pounds of fat along with several pounds of muscle. Do the math and you’ll see that weights lead to 40% greater fat loss. This isn’t a one- time finding. Research on non-lifting dieters shows that, on average, 75% of their weight loss is from fat, and 25% is from muscle. That 25% may reduce your scale weight, but it doesn’t do a lot for your reflection in the mirror. It also makes you more likely to gain back the flab you lost. However, if you weight train as you diet, you protect your hard-earned muscle and burn more fat instead.
