Hey dude. I was an avid weightlifter and runner before this and now my build is pretty average and kinda skinny/lean. It sucks, a lot. Like my entire being revolved around health/working out before all this. I still workout, but gains don’t come like they used to and I fatigue much faster than normal. I also don’t get the beloved “pump” in the gym like I used to
Over time, I think your progression of atrophy will stop. Don’t over work your body in the beginning if you’re still experiencing atrophy. I was doing that and it made me very tired. Eat well and get enough healthy proteins to prevent further atrophy.
