So for about 2 months now I have been going to the gym 2-3 times a week and trying to do walks or a short band exercise on the non gym days. Over the last 2 weeks I have gained 10 pounds. For a few years now i fluctuate between 160-165 and now i’m at 175 and haven’t been there since my fat pants days. I don’t understand how i’ve gained so much over such little time and I haven’t don’t anything differently from the usual. I would say muscle gains but i really don’t think i’ve done enough for it to be a whole 10 pounds of muscle. I wouldn’t be so concerned if i felt better, but I don’t. I feel so much bigger. Any thoughts?
