Only one way to find out. Hit the bench and start pumping. First we must set some parameters. Is this three minutes straight? That seems impossible. I did a little experiment this morning with 120 lbs. After 45 seconds my arms were noodles. 37, best form possible. With no spotter I didn't want to give it another go.I've heard similar numbers as well, but when I think of the number of pushups I can do then think about doing that many reps on bench press with 55% of my bodyweight, that seems even more challenging. But I've never actually tried it so might be completely wrong.
