I really think it's my new weight routine. Instead of upper body and lower body days, I'm doing a day for pull muscles, a day forpush muscle , and a day for just leg muscles. I know what you're thinking...but it's only one day a week for each group. True, however, for each muscle group I'm doing at least 3 different exercises, so by the time I'm done my muscles are screaming.
Despite the fatigue, I am noticing a change already in my body. It could be hallucinations due to the exhaustion, but I don't think so. I am actually wearing pants that were too tight to wear just 3 weeks ago...and they fit great today....go figure.
