Twister is a long known submission lock. The devastating crank was among the first spotted in amateur wrestling – there it was called a guillotine. It was developed in the 1920s by Cornell 1928 NCAA champion Ralph Leander Lupton. In fact Cornell’s hall of fame cites him as inventor of the move.
In the grappling world it’s called Twister and has been taught at length by Eddie Bravo in his 10th planet jiu-jitsu system.
Recently Fight to win CEO Seth Daniels shared his own brief but insightful take on the technique:
Explaining to my chiropractor @sdspineandsport how to break a human spine while he puts mine back together. As you can see this is the twister spine lock, notice the torsion effect on the vertebrae. How’s that for an adjustment. @hyperfly @musclepharm @thearmbarsoapcompany #ycth #hyperfly edit: I’m not injured this is an old photo it just showed up on my memories on fb.
