In the video example, the back of his wrist joint is not touching the ground (so his wrists are constantly engaged in the down position). The only way I am able to do PE4 is if my wrists go a full 45-degrees so the back of the wrist rests on the floor (it almost ends in a stretch). It’s impossible for my wrists to both be down but with a gap from the floor so they are engaged - there’s too much strain on the wrists.
Which technique is right?
