During heavy legs days I used to wear compression shorts under my shorts. one day, while visiting my sister in DC, i was working out at her corporate gym, a bunch of suits crowded around the stairmasters and me, I really blended in well... I forgot the regular shorts and just had bike shorts on over the compression shorts which made things that much tighter than they should have been, had every plate i could find on the 45¢ª press, pushed it up, apparently my nads shifted place under the compression shorts and when i lowered the weight it felt like sombody latched onto my nad with a vise grip.
Of course I couldnt do shit, pinned in the chair by 700+lbs and unable to speak, couldnt do shit, face turning the color of a firetruck and my arms flailing around like Richard Simmons to "Its raining men"
Suits all hopping around trying to figure out what to do, trying to PUSH the rack back up... when a trainer calmly walked over and started slide/dumping the plates off.
The crazy part was once the pressure was off my legs, THATS when I just about blacked out.
All in all a very impressive session.
