Introduction

We all have different reasons for wanting to lift weights. Undoubtedly, many of these reasons have to do with looking better. Sculpted arms and toned abs have become somewhat of a fashion statement among certain age groups. But many of us can think of more compelling and, ultimately, more satisfying reasons to lift weights. Here’s a reminder of how much weight training can benefit you:

• Keep your bones healthy. The average woman loses about 1 percent of her bone mass each year after age 35. Men are susceptible to brittle bones, too. Lifting weights can drastically slow the rate of bone loss and may even reverse the process. With strong bones, you won’t become hunched over as you age, and you’ll lower your risk of life-threatening fractures. No matter your age, it’s never too late to start strengthening your bones.
• Help control your weight. When you lose weight through dieting alone or together with some aerobic exercise (such as walking or bicycling), you lose muscle along with fat. This can be a problem: When you lose muscle, your metabolism slows down, so you’re more likely to regain the weight. By adding weight training to the mix, you can maintain (or increase) your muscle and thereby maintain (or even boost) your metabolism. Although weight training is no magic bullet for weight loss, many obesity experts consider it to be an essential part of any weight control program.
• Increase your strength. Lifting the front end of a fire truck may not be among your goals in life, but a certain amount of muscle strength does come in handy. Weight training makes it easier to haul your stacks of newspaper to the recycling bin and carry and put away your groceries. It can also keep you out of nursing care homes in your older age and help you maintain your independence. Studies show that even 90-year-olds can gain significant strength from lifting weights and regain the ability to walk and dress themselves.
• Boost your energy. Forget about hokey dietary supplements. One of the best energy boosters around comes not in a bottle but on a weight rack. When you lift weights, you have more pep in your step. You can bound to the bus stop, sail through your company’s annual charity walk-a-thon, and make it to the end of the day without feeling exhausted.
• Improve your heart health. For years we’ve known that aerobic exercise such as walking, jogging, and cycling can lower your risk of heart disease and high blood pressure. But new research suggests that weight training may offer these benefits as well. Specifically, studies show that lifting weights can lower your risk of having a heart attack or stroke by lowering your LDL (“bad”) cholesterol and reducing blood pressure.
• Improve your quality of life. Any activity that accomplishes all the above has to make you a happier, more productive, and more self-confident person. (Research suggests that weight training can even relieve clinical depression.) Of course, hoisting hunks of steel is no instant cure-all, but you’d be surprised how much satisfaction a pair of 10-pound dumbbells can bring into your life, which also improves the lives of everyone else around you.
