Below are numerous student-recorded clips of sparring & mittwork through the years between the instructor and more advanced students of varying experience levels at past locations.  Note that full-contact sparring does not happen during sessions in the beginning of a student's training, and only once students have progressed through controlled contact drills, and have the desire to spar.
