Build Muscle at 50
It’s never too late to build muscle and strength. You can build muscle no matter your age.
A proven strength training program for building muscle after 50 is to lift two or three days per week, doing 10 sets per muscle and week, with about 8–15 reps per set.
Eat a healthy high-protein diet. A protein supplement can help you increase your protein intake if you don’t get enough from your regular meals. Other helpful supplements include creatine, omega-3 fatty acids, and vitamin D.
