After 40, your body changes—but that doesn’t mean you have to slow down. Learn how to stay lean and strong with expert tips and DEXA scan data.
Turning 40 isn’t the beginning of the end—it’s the start of a new fitness chapter. But your body does change, and ignoring those shifts is what leads to the dreaded “middle-age spread,” energy crashes, and stalled strength.
Here’s what actually happens—and how to fight back with data-driven precision.
You’re not imagining it—your metabolism, hormones, and recovery all shift after 40.
You can lose up to 1% of muscle mass per year after 40 if you’re not actively training. Less muscle = lower metabolism.
You start storing more visceral fat (the dangerous kind around your organs), especially in the belly—even if your scale weight stays the same.
Testosterone, growth hormone, and estrogen drop. That affects muscle building, recovery, and fat storage.
Bone loss accelerates, especially for women post-menopause—raising the risk of fractures.
More inflammation, slower healing, and greater injury risk from high-impact training.
The solution isn’t “go harder”—it’s train smarter and track what matters. Here’s your science-backed game plan:
Resistance training is your best friend for preserving and gaining lean muscle. Focus on:
You need more protein than you did in your 20s. Aim for 0.8–1g per pound of body weight daily to support muscle retention.
Low-intensity movement helps manage cortisol and burn fat without overtaxing recovery.
Stretching, sleep optimization, and rest days are critical for injury prevention and hormone health.
You can’t see visceral fat, but it drives metabolic disease. Track it with a DEXA scan, not a scale.
A monthly or bi-monthly DEXA scan gives you a detailed view of your internal health:
Most “fit-looking” people over 40 have no idea what’s going on under the surface. A 6-minute DEXA scan gives you the truth—so you can adapt and stay ahead.
You can either drift into slow decline—or get proactive and optimize your health with real data.
The best athletes and longevity experts don’t guess. They test, adjust, and improve—one DEXA scan at a time.
