Today there were two 18 year old kids in the gym (wearing class of 2008 clothing). My size I guess, maybe 180 pounds.
They were high fiving, acting all obnoxious, loud, etc. Bench pressing 185 for reps. I quietly set up and bench 135 for a warmup and you can tell they look and mutter something.
I complete a second set with 185, and I see them counting reps then assisting each other with the spot, to do exactly more than my 1 rep. They're still smug.
Without a spotter, I put 225 on the bar and do 8 clean reps. I sit up and calmly look over at them and await their response. They put 225 on the bar. Neither kid can do it. They unrack the 225, and they leave the bench area and walk out the door to their cars.
My motivation is to stay ahead of punk ass kids.
