Hi, Ray and Mike @mikem75 - My husband lost the ability to run several years ago. He enjoyed running as part of his overall workout. He played a lot of sports when younger, mainly football then TKD into his 40's, and has been a floor installer by trade... you see where I'm going with this? The knees never stood a chance!

He'll be 60 this year and had a knee replacement 2 years ago followed by an unfortunate revision on same knee 1 year ago. There were complications during the revision which left his bend limited. Now he is hoping to at least get enough bend to ride his bike.

He also says how much he misses running. One thing I'll throw out is that he does enjoy kayaking. Not sure if that is possible for either one of you gents, pretty low getting in and out. It always stinks giving up things you love. I relate and have had to look outside the box for new joys, as well.

I enjoy walking but am time limited so I like to visit my nearby park and rest on the bench to watch the kids and pets play. Have you found any other "void fillers" (besides biking) that you've tried and found helpful? Maybe something to give the feet a moderated break?
