Glad you touched on cramping towards the end because that's what was instantly going through my mind when you said to maximally contract the hamstring in that shortened position :D
Probably because they’re not you and you’re only one of 8 billion people on the planet…so what happens to you might not be the center of the universe for everyone else. Are you pretending to have the self-awareness of a third grader, or is this a real issue for you? And the answer to your inane question is: they’re complaining about cramping because they felt cramping…because cramping can happen when muscles are flexed in positions they’re not accustomed to. Was that really the extraordinary intellectual journey you wanted it to be?
Cramps as "neurological confusion" in the system is the best take away for me from this! Thanks!

Read it, liked it, tried it and got reasured in less then 30 seconds!
Did he get your foot. That looked like it hurt, but you sucked it up well and the hamstring control is impressive
Years of toes/foot strengthing accompanied with kicking people has built up some resiliency! lol
amazing video. especially the nervous system explanation!
Excellent video!
I cramped immediately! 😆
I loled at 0:50

Interesting, but the hamstrings usually pull in the long (eccentric) position.
Man I did this and cramped the fuck up right away
Gotta confuse the brain, right?
I thought that goofy looking guy on the left was Bryan callen doing a pose haha

This is going to be random, but Dr Spina where did you get your T-Shirt?

That dude on the right needs to stretch his hamstring....
My hamstrings are cramping so badly lmfao. Do I just keep doing them until I don’t cramp anymore?😂
“I can’t hear you over the obnoxious music.”
What?
“I SAID I CAN’T HEAR YOU OVER THE OBNOXIOUS MUSIC.”
Why is everyone complaining about cramping? It was fine for me.
