Krekels vlogen mee in 1998 met NASA's Neurolab-missie om te bestuderen hoe zwaartekrachtsensoren zich in de ruimte ontwikkelen.

Nobody’s telling you to stop running, the point is that after 40 lifting has to become foundational alongside it.

The protocol: two to three resistance sessions a week, squats, deadlifts, rows, pressing, with progressive overload. If the last two reps feel easy, it isn’t heavy enough. Add zone two cardio, and walk daily.

Muscle is also your largest metabolically active tissue, regulating glucose disposal and releasing anti-inflammatory signals that protect the brain and cardiovascular system. Cardio supports your heart. Muscle determines your metabolic future.

. Both raise BDNF, your brain’s growth factor.

Resistance training showed strong improvements in cognitive function alongside the known benefits of aerobic exercise, and the researchers concluded it should be a primary intervention for protecting the aging brain.

And excessive endurance work without recovery can elevate cortisol, which after 40 accelerates muscle breakdown and disrupts sleep.

Muscle mass declines 3 to 8% per decade, testosterone and growth hormone drop, insulin sensitivity decreases, and the brain begins losing volume in regions tied to memory. Cardio helps your heart and brain, but it doesn’t preserve muscle the way resistance training does.

After 40, cardio alone isn’t keeping you young. The research now puts lifting heavy in the same tier for protecting your brain, and lifelong runners aren’t going to like it.

What happens after 40 changes which exercise you can’t afford to skip.

Sarcopenia is cruel because it takes decades and you feel nothing, until the day something you’ve always done suddenly feels hard. But it’s one of the only forms of aging you can genuinely reverse.

Squats, lunges, push-ups, rows, bands, carries. Studies show 2 to 3 sessions a week rebuild strength even after 60. Pair it with 1.2 to 1.6g of protein per kg of bodyweight, spread as 25 to 30g per meal.

And low muscle mass predicts early death more strongly than obesity or blood pressure.

The good news: the reversal window is real, at any age. Muscle only rebuilds under resistance, so walking alone won’t do it.

Which matters, because muscle is medicine. It’s your largest glucose sink, so more muscle means better insulin sensitivity. Trained muscle pulls on bone and triggers growth, a top defense against osteoporosis. Balance plus resistance training cuts falls by about a third

It’s never one cause, it’s a stack. Low protein & crash diets burn muscle alongside fat, leaving you lighter but weaker. Pregnancy makes your own muscle the reserve. & falling estrogen speeds breakdown while slowing repair, at exactly the age when almost no women lift.

Peak muscle at 30, then 3 to 8% lost per decade, perimenopause at 40 to 45 accelerating everything as estrogen drops, and up to 1% every single year after 50. You can lose a third of your strength between 30 and 60.

Sarcopenia is muscle you can’t feel leaving. Strength fades until everyday tasks quietly get harder. It begins silently in your 30s, and women start with less muscle, so it costs them sooner.

Women lose 3 to 8% of their muscle every decade after 30. It’s called sarcopenia. Here’s how to reverse it.

. And after 40 this stops being optional: muscle leaves faster and fat settles deeper.

The good news: a trap you can name is a trap you can leave. You don’t need willpower against the food and the couch, you need two levers, what you put in, and loading your body so muscle comes back.
