You are 255lbs juiced out of your mind prepping for a show 4 months ago. I am 225lbs and my video is from today. I would not consider that a struggle. My set was also totally solid. I wasn't even counting reps just doing some to prove a point. It wasn't even supposed to be arm day for me.
I did that at the end of training you did it fresh. I was in a calorie deficit. I also had more reps in the tank. Of course you were counting, your not that egoless. You will spend your last dying moments on this planet arguing with people.
Your "bitch" might have held some credit if you surpassed my rep count, it just makes you look like a fool trying to act hard.
Your biceps are good and strong, not at my level of course but pretty good. Pity we cant compare basically any other lift because your body is falling apart.
