I cannot jump off of one foot right now (last year or so). NOT the old "I can jump higher off of 2 feet than 1." I am having a heck of a time trying to jump off of one, period. I can jump okay off of 2 feet, but had always been better jumping off of 1. In the last year or so, I've noticed that I cannot seem to jump off of one foot when I get a running start. I've been working foam roller, IT Band stretching, glute stretching, goblet squats for improved flexibility, etc.
Note - I can squat a fair amount of weight with pretty good form, but can't hardly do a lunge (even weightless). I have super tight psoas and have been working to stretch those.
*It's a random issue, but renders me virtually worthless on a basketball court (running and jumping are a necessity).
