My good friend and long time training partner is a 10 sets of 10 with 405 junkie.
We often call each other after crazy workouts. Of course, whatever the workout was, the other has to do it the next time they train that bodypart. It's typical male insecurity/alpha male syndrome.
Last summer he called me up to tell me about the leg workout he had.
He went to the gym in the morning and did:
10 sets of 10 with 405 on squats
leg press
hack squats
leg extensions
leg curls
I don't remember the sets and reps for those exercises, because all I could focus on was what he said he did later that day.
He went back to the gym, 5 hours after the first workout, and did 10 sets of 10 with 405 again.
"to see if I could do it" was his reasoning when I asked.
I've trained with many of the strongest people in the world. I've trained with bodybuilders and powerlifters in every state, so I'm way past the point of believing that in some dungeon somewhere, there lurks a man who's workouts put everyone to shame. I know what strong is.
That's a crazy workout.
And, I didn't try to do it. I admitted defeat.
