Video #1 - Very nice! I can see in this video we've made some corrections. Approach has a nice circular turn now - see thet lean into the turn on step 9? Exactly what we want! Your arms both back on 9 and up into Finish Position on 10 is GREAT - wish all the other jumpers could do this. Shoulders still rotating away from the bar early before step 10. Good vertical release of the jump and a nice arch as you reach the top of the jump. You can see the break the moment you start to fall toward the pit - it is very hard to learn to hold the arch as you begin to fall. Video #2 - This approach has a bit of a step-out on step 7, which puts 8-9-10 in a straighter line again. Pacing is also very flat and slow for this height. Jump just dies before you get to the top because no energy. Video #3 - MUCH better step 7 across onto the J. Bad camera work by me, but I think this jump had the height and you just broke it straight down onto the crossbar. Video #4 - Your new PR 5'0" - CONGRATULATIONS!!! I see a lot of potential in this jump for you to keep improving as you learn the system...
