The Study

O.4.1-5 An online lifestyle intervention consisting of resistance exercise and advice on protein intake improves leg muscle strength and physical functioning in older adults

In simple terms

This study watched what happened to 19 older people who did online workouts and ate more protein for 24 weeks. Their legs got stronger, but we don’t know if it was because of the program or just because they got luckier, older, or tried harder on their own. It’s like noticing your plant grew after you watered it — but you didn’t test if it would’ve grown without water.
