I'm not a terribly strong guy, especially by T-Nation standards, but two times in my life I've had opponents comment on how strong I felt. Both times I didn't cut any weight, just showed up and weighed in. Once I weighed in at 197 for an MMA fight at 205, afterwards opponent said "I'm not saying you look wimpy or anything, but you are WAY stronger than you look." Weighed in at 201 for a 208 limit in a BJJ tournament this weekend, guy who beat me in the finals said "Dude, you are strong as a MOTHERFUCKER!"
Before anyone thinks I'm just tooting my own horn, another time I cut to 170, came into the ring at about 182 to fight a 155 lber who couldn't find an opponent and came in at 165. He beat the shit out of me haha
Point is, does anyone else just feel 10x better when they don't cut? For me it makes such a difference that I'd rather go against bigger guys than to have to cut and compete with guys my size or smaller. It just doesn't give me the advantage it does for other people.
(For clarity, I mean cutting water weight the day or two leading up to weigh ins, not dropping weight through diet and training.)
