It takes about 10hrs a day 5-7 days a week of practicing and slamming into the ground over and over again until u nail it regularly. It takes unreal power, balance, body control and complete disregard for your body at times. Imagine trying to do a long combo in a game and u have to memorize a bunch of buttons to pull it off…..that’s how it is trying to get your body where it needs to be to transition from 1 move to the next…..if go big and u get it wrong you’re slamming into the ground. It’s some of the hardest training a person can put themselves through (outside of the military)
