I did calf raises every day for 30 days and it massively reduced my knee pain and made running easier

A woman stands at a bar in a studio doing calf raises. She is on her tip toes. In front of her is a mirror, reflecting the green leafy plant behind her. We also see a storage unit, stocked with Pilates balls. .

A lot of people neglect their calf muscles when they work out—I know I barely gave mine a second thought.

But after a recent visit to my physical therapist, I discovered I'd developed a weakness in my calves that was contributing to persistent pain in both knees.
