Anyone out there do CrossFit after having the sleeve? I had my surgery December of last year...and I started doing CrossFit again shortly after that. I’ve lost 80+ lbs so far and have hit a stall (about a month) anyways I feel like I’m still loosing weight be clothes fit smaller and all that but the scale says differently. I’m thinking that I’m gaining muscle but not positive. I guess my question is has anyone else had that problem?

If you are doing a lot of weight training, it is likely that you have increased lean body mass. The scales don't tell the full story as you can see, clothes are fitting better but the scales do not reflect that. Don't let the scale be your only measure of success.

Other things could be impacting on the stall you haven't mentioned about your food intake/portion control or water intake. What foods you are eating etc.
