Hitting a Wall with My Handstand Push-Ups

I’ve been coaching CrossFit for a while now, but my own handstand push-ups have been stuck in a rut for months. No matter how many I programmed, I just couldn’t seem to add reps or get more consistent. I realized I was relying too much on momentum and my lockout was weak. What finally helped was scaling back to strict deficit push-ups for a few weeks to really build that strength off the wall. I also started focusing on my breathing during the descent sounds simple, but it made a huge difference in control. Has anyone else found that going back to basics with a strict variation helped them push past a plateau? What tweaks have worked for you on other lifts?
