8 Reasons you should start weightlifting now!
Indulge me for a moment by flexing your right arm. Assuming you have an average build, and trust messss, you do, your arm is packing about five pounds of muscle. It represents nearly 10 percent of the total muscle on your body. Now, imagine that muscle gone. No biceps, no triceps, only a jiggly mass of skin and fat covering your bones from your shoulder down to your fingertips.
That five pounds of muscle is about the same amount most men lose between the ages of 24 and 50. And that number doubles by the time they’re 60. In fact, once a man passes the half-century mark, he can expect to lose 1% of his muscle each year for the rest of his life. That is, unless he does something about it. And there’s good reason for intervention: the natural erosion of muscle and strength that comes with ageing leads directly to weak bones, stiff joints, and a slumped posture, and increases your risk of developing heart disease, diabetes, and a host of other maladies.
But there’s no reason you can’t maintain a healthy, strong musculature well into your 90s if you use man’s most effective anti-ageing weapon: resistance training. Lifting weights regularly signals your body to fight to keep your muscle. That means a longer, healthier life. And we can prove it. Here’s why every man should be lifting weights even if he doesn’t care about the size of his biceps.
Lifting is good for the grey matter
Researchers at the University of Michigan found that men who performed three total-body weight workouts per week for 2 months lowered their blood-pressure readings by an average of eight points. That’s enough to reduce the risk of a stroke by 40%.
It strengthens bones
As you age; you lose bone mass, increasing the likelihood that you’ll one day suffer a debilitating fracture in your hips or vertebrae. That’s even worse than it sounds, since Mayo Clinic researchers found that 30% of men die within a year of breaking a hip. In addition, significant bone loss in your spine can result in perpetually rounded shoulders and dowager’s hump, eventually transforming you into a 21st-century Quasimodo. Resistance training can help you avoid this fate. Recent research in the Journal of Applied Physiology found that men who lifted weights for 16 weeks increased their hip-bone density by 3.8% and raised their blood levels of osteocalcin (a marker of bone growth) by 19%.
You’ll get more years out of your old jeans
For every pound of muscle a man loses, he gains a pound of fat. In other words, that five pounds of muscle that most men lose by age 50 is typically replaced by five pounds of fat. Not only does that make you look flabby, but it also increases your pant size, even if your scale-weight remains the same. One pound of fat takes up 18% more space on your body than one pound of muscle. Bottom line: keep your muscle, and you’ll fend off fat.
Maybe you’ll touch your toes again!
Between the ages of 30 and 70, flexibility decreases 20 to 50%, making it harder for your joints to move through their full range of motion. For example, if you can’t squat down until the backs of your thighs touch your calves (most men can’t), you have tight hip flexors, which limits movement at the knees, setting you up for injury. Researchers have found that three full-body workouts a week for 16 weeks increased flexibility of the hips and shoulders by more than 30% and improved sit-and-reach test scores by 11%. So there’s still hope that someday you may once again be able to touch your toes. Weight lifting can get you there.
It negates the danger of eating carbs
Every time you eat fast-burning carbohydrates, such as white bread, rice, and potatoes, your level of insulin, a hormone that helps keep your blood sugar normal, rises dramatically. That’s a problem because consistently elevated insulin increases your risk of diabetes and heart disease. But lifting can help. Researchers at the University of Massachusetts found that men who added two full-body weight workouts a week to their existing aerobic exercise program, had insulin levels that were 25% lower after a meal that was high in carbohydrates, than the levels of men who performed the same aerobic exercise program, but didn’t lift weights.
You’ll keep more fast-twitch muscles
It’s not just the quantity of the muscle you lose that’s important to pay attention to, but also the quality. The ageing process reduces the size of your fast-twitch muscle fibres by up to 50% but shrinks the size of slow-twitch fibres by less than 25%. That’s significant because your fast-twitch fibres are the muscles largely responsible for generating strength and power (the key to peak sports performance when you’re young) and helping you easily get out of a chair when you’re old.
You’ll rev your metabolism
Your body requires energy to digest food. So every time you eat, you actually burn some of the calories you’ve just consumed – typically, 15 to 20%. However, you will burn 73% more calories when you eat right after you lift weights. Scientists in the Netherlands calculated that men who lifted weights two times a week for 18 weeks burned an average of 9% more calories a day than non-lifters did. That’s enough for the average man to lose 25 pounds in a year without making any changes to his diet.
Weightlifting affects mood
Older men who performed three weight workouts a week for six months improve their scores on measures of confusion, tension, anger, and overall mood. Although unsure of the mechanism, researchers say it could simply be a feeling of accomplishment from having become fit and more confident in themselves. Participants in a study reversed a decade of age-related muscle loss and fat gain, by adding four pounds of muscle and dropping three pounds of fat, while increasing strength by an average of 42%. Those results would improve anyone’s mood.
