As a personal trainer, many clients come to me with knee issues, looking for the best exercises to strengthen them. Strong knees are essential for preventing injuries and supporting you in everyday movements like walking, bending, climbing and standing.

I saw this four-move knee-strengthening workout by mobility coach Anthony Green and I love its simplicity. You can do these bodyweight moves anywhere, without any equipment. Incorporate them into your regular fitness routine—and if you’d like more variety, I’ve added six other knee-friendly movements to try.
