Here's a funny story about the MT back kick.
Do you guys know who Seth Petruzelli is? He's one of the heavyweights on this season of TUF. He trained here at the gym I go to for many years. He was around 250 pounds at the time of this story. His sparring partner, Brewster, was about 5'8" and only 150 pounds at the time.
So coach is trying to get Brewster to practice using his back kicks in the situation I described a few posts earlier. And Brewster is dragging his feet (figuratively) because he doesn't think the back kick has any use. At this point in time, his attitude was, "show me my right hand and my leg kick and i'm fine".
So he's in the ring with Seth later that night, who is being extra careful due to the 100 pound weight difference. Brewster misses on a leg kick, and goes for the back kick like I described but because he's been half-assing it the whole day he misses Seth's stomach (the intended target) and catches Seth right in the nuts with this fucking mule kick. Seth just took a step back and slumped down in the corner. He was cool about it but obviously wasn't too happy.
So, Brewster thinks a little differently about the MT back kicks now.
