Hurt my shoulders so badly playing Beat Saber last tuesday I could barely get out of bed the next morning.
Now nearly fully recovered and turned the game on, started using more wrist/elbow and less shoulder to avoid hurting it, and holy shit this is the strat. was barely comfortable with 5.5 star tracks before, but now easily doing 6-7 star tracks. 
Cant wait until I fully recover and can get back to playing it for 4 hours at a time
