I made my video as I see it on the pro's and con's of leaning back out of range from Israel Adesanya at UFC 243. Generally it is used by elite level kickboxers as a head kick defense as much as anything. A lot of old school boxing trainers hate that movement style because it leaves you susceptible to guys who double and triple up on their punches. What do you think about it? Is leaning back a valid strategy. I guess you can say for self defense you need to be more worried about defending yourself against punches as it is unlikely you are going to come across a guy who is going to try a headkick with their shin in a self defense scenario.
