Cyndie Myst is a professional martial arts (Taekwondo) veteran and instructor. She was nice enough to take some time to show us a few ways in which groin strikes are used when defending again a front-facing attacker. She goes over a few moves, explaining them in detail and miming each hit, but also delivers a REAL (and HARD) blow to the balls for each move. Psymon is visibly scared throughout the video. :) Thanks Cyndie!
