Resistance Training and Healthy Aging: What the Evidence Says About Longevity in Your 30s, 40s, and 50s

Most men don't think much about aging until something forces the issue: a lift that used to feel easy, stairs that leave you winded, or a waistline that expanded despite no real change in habits. Fortunately, the research on longevity and healthy aging is largely consistent on what to do. Resistance training, plainly lifting weights regularly, is one of the most well-supported interventions available for extending both lifespan and health span, the stretch of years you spend actually capable of doing the things you want to do. This is not a supplement pitch or a training trend. It is the current body of evidence built over decades of research, and it applies directly to both men and women who may be beginning to feel the effects of aging.

The Clock Starts Earlier Than Most Men Realize

Muscle loss, clinically known as sarcopenia, does not wait for retirement. Muscle mass typically declines by 3% to 8% per decade starting around age 30, with the rate of loss accelerating after age 60. Peak muscular strength and power are usually reached between the ages of 25 and 35, after which decline is slow at first, then speeds up with advancing age. By the time most people notice a real difference in how they move, feel, or perform, the underlying process has likely been running for a decade or more.

Q:

Is there any reduction that should be made since these lifts are on Planet Fitness machines rather than dead lifts with free weights? All of the machines use some sort of pulley system, so I can’t compare with a guy who does free weights. Is there any sort of translation routine for that?

That’s a thoughtful question. The short answer is not with a single universal conversion factor.

Here’s why:

The weight stack is intended to represent the external resistance you are lifting. Manufacturers usually design the pulley ratios so the number on the stack is the effective resistance at the handle, even if multiple pulleys are involved.

However, different machine designs vary. Some use a 1:1 ratio, while others use 2:1 or other mechanical advantages. The stack may say 70 lb, but the force at the handle could be more or less depending on the machine and how the manufacturer labels it.

Free weights also aren’t directly comparable because they require much more stabilization and coordination. A 70 lb chest press machine is not equivalent to a 70 lb barbell bench press, even if the external load is similar.

Steak and Butter Gal is on a carnivore diet and is way over the top with her beliefs. But I learn a bit every time I watch one of her videos.

No, I am NOT a carnivore, I am closer to a vegetarian who like David Sinclaire, thinks that a vegetarian diet is healthier.
