I am concerned about knee pain.

A few years ago, I suddenly had knee pain and visited the hospital. They said the cartilage was slightly worn down.

I am only taking knee supplements without receiving any special treatment.

I go for a walk every morning, but sometimes I feel pain.

They say I should do leg strength exercises, but I just end up doing only walking cardio exercises.

What supplements are most helpful for knee cartilage?

I hear that swimming is good, but I don't have the courage to try.

What kind of leg strength exercises are you doing?
