Greg Jackson co-owns one of the top MMA training centers in the world, Jackson Wink MMA Academy, training many successful fighters like Holly Holm, Jon Jones, and Michelle Waterson. He founded his own martial art, Gaidojutsu, combining techniques from catch wrestling and kickboxing with basic Brazilian Jiu-Jitsu and judo locks.

Jackson volunteered his time to FightBack, a week-long virtual live training event featuring some of the best martial artists. The event raised money for Red Cross to support first responders and the medical professionals on the front lines against COVID-19.

Jackson's seminar covered "mirror stance," the boxing/kickboxing term for when two combatants are in mismatched stances (one is southpaw and the other is orthodox), and how this affects your strategy and move set. If you participate in any stand-up striking art, this is a don't-miss session!
