I'm (ahem) 50-something (early fifties). Four weeks ago I sterted this progam and was thoroughly enjoying it. Week one went well. Week 2? My knees hurt more each time time and the final time just painful so I stopped. I've continued walking only and stretching. I've also started a glucosamine/chondroitin and gelatin routine. My knees felt better the last few days so I tried just a little light jog today. No go. My knees hurt again. So I walked only to make up the thirty-minute workout.
The pain (if I'm sitting in a chair, feet on the floor) is on the inside of each knee. About 1:30 for the left knee and about 10:30 for the right knee. Just below my kneecaps.
Any advice or suggestions would be great. I've registered for a 5k run in October, and I sure would like to be able to run it.
