Most adults over 50 have heard the same advice for years: stay active. Walk more. Take the stairs.
It’s good advice, but it leaves out the part that matters most. Muscle loss starts in your 30s and speeds up after 50, and walking alone doesn’t stop it. You can feel fine and keep a steady weight while getting a little weaker every year. Then one day, getting up off the floor or carrying a suitcase upstairs feels harder than it should.
