i'm at a comfy 228 right now... trying to break through 230 on my way to 240/250.
when i first got up around 220 i felt slow and wasn't used to the weight yet, a few months after i'm ok, I think my body has reach a homeostasis at this weight... sure i'm not as quick as I was at 180 but that's to be expected.
6' with socks on.
I do find I sweat a helluva lot more in certain situations. Like in a suit, on christmas eve in church. I was sitting there sweating my ass off. Not stimulant induced either.
