I want you to think of a fighter throwing a punch. You can throw a punch with just your arm, just like you can bench press with just your arms, but... a STRONG punch starts from the floor just like a strong bench press starts from the floor... When you initiate that leg drive, instead of trying to drive your butt upward like it's trying to go straight to the ceiling, I want you to try to push towards your head like you would literally slide backwards towards the uprights.
