After 40, Your Body Is Playing by Different Rules. Are You?

Men begin losing roughly 1% of testosterone per year after age 30. By 40, muscle loss (sarcopenia) can accelerate, lowering metabolism and making it harder to maintain strength even with consistent training.

Hormonal shifts cause fat to preferentially deposit around the abdomen and internal organs - visceral fat. Unlike subcutaneous fat, visceral fat is directly linked to cardiovascular disease, insulin resistance, and metabolic dysfunction.

Your resting calorie burn decreases as muscle mass drops. The same calorie intake that maintained your weight at 35 now causes gradual gain. Most men don't know their actual metabolic rate - and most calorie apps get it significantly wrong.

VO2 Max - your body's aerobic capacity - naturally decreases with age, but the rate of decline is highly trainable. Men who know their VO2 Max can train precisely to maintain and even improve it well into their 50s and 60s. 

The standard health checkup measures blood pressure, cholesterol, and weight. But none of that tells you how much visceral fat you're carrying, how much muscle you have, what your metabolism actually burns, or how your aerobic fitness compares to your peers. DEXA and VO2 Max testing do. These numbers tell the story your annual physical can't. 

DEXA Body Composition

Precise body fat %, lean muscle mass in lbs, visceral fat (the dangerous kind), and bone mineral density. Includes left-right muscle symmetry - a key indicator of injury risk and athletic decline.

Visceral Fat: The Number That Matters

DEXA is the gold standard for non-invasive visceral fat measurement. The report gives you your visceral adipose tissue in lbs - not a generic "zone 1-10 rating" like some other devices provide, but an actual weight measurement.

VO2 Max Testing

Know your true aerobic capacity and compare it to age-matched norms for men. Identify your precise training zones so your cardio is actually improving your fitness - not just burning calories.

RMR (Metabolic Testing)

Find out exactly how many calories your body burns at rest. Men over 40 often have a metabolic rate 200–400 calories below standard calculator estimates - meaning they've been eating at a hidden surplus for years.

•  Men in their 40s, 50s, and 60s noticing changes in body composition despite staying active
• Men on testosterone therapy (TRT) wanting to verify it's actually improving lean mass
• Men on GLP-1 medications who want to track fat vs. muscle loss
• Guys who've always been active but feel like the same effort isn't producing the same results
• Men whose doctors have flagged elevated blood pressure, cholesterol, or blood sugar - and want more context
• Anyone who wants to know what their body is actually made of

Recommended combo: DEXA + VO2 Max + RMR. Together these three tests give you a complete metabolic snapshot - your body composition, your aerobic engine capacity, and your daily calorie needs. Many clients combine these with our SphygmoCor arterial assessment for a total cardiovascular health workup outside a hospital setting.

What's more, you can add on bloodwork to track various chemicals like testosterone!
