Also, what's with "holding the bed with my toes and fists" ? I don't picture that really well.
The bed didn't have enough space for him to fit with its legs on the floor. I imagine he was lying face-up under the bed, with his arms outstretched, fists balled up supporting one end of the bed (under strut). At the other end, his heels would have been on the floor, with his toes bearing the weight of the bed

Hopefully the assailant only sat up on the bed after our guy tore it open and slid inside the frame. Still, he stayed hours at first, holding the bed 10 centimeters from the ground.
I wondered this as well. He did say he has had significant training, but honestly, I think this was just pure luck.
Just my hunch at least. Untidy bed is already ”broken”.
