I didn't gym for 6 weeks due to surgery, just light walking and i was loosing weight.
Now i'm back at the gym and i've actually gained weight and it's harder to drop off than it was when i didn't go. When I wasn't going I was easily loosing 1lb and a half a week. But now I'm 4lbs heavier after a few weeks back at the gym, same diet. How is this possible? Very frustrating.
