Q: I have suffered knee problems in the past few years and had to stop running. Though I know swimming is the best exercise, I am petrified of water. Anything you can recommend that is light on the knees but high on cardio?
I can relate to being petrified of water. I signed up for 3 triathlons, only to back out because I couldn't get into the water. Swimming is excellent for people with knee problems.
I highly suggest you finding a swim instructor or class for adult beginner swimmers and ease your way into the water. I did and doing my first triathlon this summer! Another great option is water running. You do it in a pool, your head stays out of the water and it's a great form of cardio and easy on the knees! If you want to stay on land, the elliptical machine is low impact and can get your heart rate up. Also, walking on a treadmill at an incline, not only burns calories, but works at toning your legs. If you haven't already, check with your Dr or physical therapist regarding ways to strengthen up the knee and areas around it. Good luck!
