Done for 7 reps. Very natural. Have no idea what I could have done gassed - never tried.
I weighed 255 at the time. A nice, chubby, permabulk football 255. Not very pretty. Thought being strong was boss. I was wrong. Turns out girls really aren't that impressed with how often you can bench 315. The only people who cared were the other guys I bounced with at the bar, and the guys on the team. None were sufficient to replace female attention.
Note: I now rarely bench over 135, and do sets of super slomo reps totalling about 50 per set. Pecs have never been better, shoulders are healthier. Girls say they like the pecs. Mission accomplished. I tried 315 a few weeks ago to see what I could do for shits and giggles. Did 3 reps. Felt like shoulders would explode. Not natural.
