Tim, check with the trainer available at the Y to help with other cardio machines and consider adding strength training, water walking if there is a pool at the Y.  We need to change up our exercises every few weeks to keep our bodies adapting.  Try to increase the incline, vary the speed.  I am impressed with your staying with the exercise.  Keep it up.

Hi Tim,

      Kathy gave you good advice. I just wanted to say I think you are doing great. Asking questions about how to improve is just what you need to do. You can do this. I have faith in you.    Mag
