Total Knee Replacement Out There? Exercise Ideas?

HI All,

I have been a member of this site for some time. I was curious if there were any folks out here with Total Knee Replacements? I am curious what you are doing for exercise programs. I had a TKR in January of this year (I'm only 46!). I am finally released from PT and have started doing Aqua Zumba Classes, spin, and pilates. Oh yeah, and riding my moutain bike.

I am curious about the other programs though.. Like Crossfit, P90 etc. Are any of you able to do these w/ TKR?

Thanks a bunch!
Edie
