I've been "stuck" on the Deck Squat (PE5) for a couple months. I have plenty of strength to do body weight squats, but I seem to lack the flexibility to do a full deck squat. Or so I thought - recently discovered if I pull my legs closer to my chest with my hands as I'm rolling back up, I can usually pop right up. Without assistance pulling my legs in, I guess my feet/heels aren't landing close enough to my butt and I end up half standing up and half falling/stumbling backwards.
Any thoughts on what the issue(s) might be? I seem to have the range of motion, but not enough strength somewhere to pull my legs in close enough without assistance (hands).
