Hi Elaine, I just turned 53 yesterday, but of course I say I'm 39!

I don't know what the clicking noise is that you're hearing. Be sure to warm up first and then slowly build up your reps. I have several issues to deal with. My carpal tunnel is so bad I'm in a wrist splint most of the time and I have sciatica (left side). Lots of stuff I can't do, but I do what I can.

I'm thinking of trying pilates classes. Supposed to be non-stressful. I can't run at all but I can do treadmill to warm up. No bike, hurts sciatica.

Why don't you tell me what you are doing, I'd be interested in that. Good luck, HL
