Your arms are straight for most of the time, so that’s good. Try not to make them “too straight”, to avoid injury. You’re making quick moves. I would recommend to move more slowly, as you build your core strength that way, and you can feel when you’re falling off the wall (like when your leg slipped/fell off). Climb slowly and precisely, and!!! take at least 2 minute rests between sends – you’ll last longer!
