3. Your Clothes Will Fit Better
If you don’t lift weights, you can say goodbye to your biceps. Research shows that between the ages of 30 and 50, you’re likely to lose 10 percent of the total muscle on your body. And that number will double by the time you’re 60.
Worse yet, it’s likely that lost muscle is replaced by fat over time, according to a study in theAmerican Journal of Clinical Nutrition. The scientists found that even people who maintained their body weight for up to 38 years lost three pounds of muscle and added three pounds of fat every decade. Not only does that make you look flabby, it increases your waist size. That’s because one pound of fat takes up 18 percent more space on your body than one pound of muscle. Thankfully, regular resistance training can prevent this fate. Just remember this muscle motto: Use it, so you don’t lose it. After all, nothing good comes of that.
