Ever tried a Jiu Jitsu submission that shouldn’t work, but actually does? This rib-crush technique doesn’t use a joint lock or a choke, but by throwing your opponent’s hands over your head, locking an S-grip around your own quads, and squeezing their ribs, you completely stop them from being able to breathe. At just 30% strength, it’s enough to force a quick tap or get them to turn away so you can easily take their back. What other techniques do you know that shouldn’t work but do? Let me know in the comments! #jiujitsu #combatsports #martialarts
