As a Personal Trainer and after years of working in Physical Therapy, I know from many women that they can't exercise or are limited to only walking because they have "bad knees."
As we age, our cartilage wears away, causing osteoarthritis in the joints, especially the knees.
But there are natural ways to prevent knee pain, keep osteoarthritis at bay, and build leg strength to improve mobility, strength, and even put off getting a knee replacement for a long time.
