After 40, we lose 3-8% of muscle mass every decade. After 60, it accelerates.
Here's the cruel twist: the less we move, the faster we lose muscle. And the weaker we get, the less confident we feel moving. It becomes a trap.
But scientists now know this isn't just "getting old." It's about mitochondria — the tiny power generators inside every muscle cell. As we age, these engines break down. Damaged ones pile up. Energy drops. Muscles weaken.
The good news? Researchers have found a way to help the body clear out this cellular damage — even when exercise alone isn't enough.
