I had the sleeve on May 28 then had to have knee surgery on July 29 I have lost 47 pounds but need ideas for some type of Exercise that I can still be doing to help not to loose any ground

Have you considered swimming or aqua aerobics? It's a no-impact workout that shouldn't hurt your knee but both burn a good amount of calories.

I get my stitches out Friday so I'm hoping to find somewhere after that

My knees feel better after a bike ride?

I will try it

I have a bad hip (needs replacement) so swim laps, do aqua fit and cycle. I'm losing weight and inches steadily.
