I've actually built a lot more shoulder and back muscle lifting weights than thigh muscles from squats, or at least more that I can notice. I'm still pretty weak in the upper body, though. I'm pretty much stuck trying to bench more than 75lbs. I'm just trying to become the best version of me. I really don't think I can get any slimmer than I am without causing damage to myself from undereating or over-exercising.
