Hi, I have a question about One Step #1 in yellow to green belt DVD. When Sensei Jon is doing the reverse punch, he brings his left hand to the side, but in the Breakdown of this One Step he leaves his hand up, still blocking the attacker’s hand. So which variation should I use? I think bringing the hand to the side gives the body more torque, thus more power to the punch, also the left hand is now ready for another move, so I guess this variation might be better, but I want to be sure. Thank you.
