If you can bench 135 lbs for 100 reps that's the equivalent of a 580 bench, let that sink in.
Hahahahahahahahahahahaha
haha
Yeah, okay.
To lift heavy you MUST train heavy.
If you get your 135 rep count to 100, but never venture north of three, the possibility you will succeed with 580 is zero.
You will be pinned under 315, even.
