getfitdoc said:at about 2:30 you'll see this guy run up some walls. watch how he keeps his feet moving when he kinda gets stuck. thats what you have to do.
get that initial jump and leg drive into and up the wall, get the hands on the top, then keep driving you legs up.
If you can't practice on a wall i would do some intense sets of mountain climbers, just to get those legs used to driving.
