I’m just posting this for guys that might be interested but yesterday was my first day in using the Mata Ray device for Max effort squats.The bar weight was 500lbs with 20lbs of chains on each side for 3 easy reps but my last two reps I should have went deeper( I feel).
Anyhow, today I can feel the soreness in places that I never felt before (upper back in a VERY specific area).You guys should try it; the device is only 50 bucks and it feels so snug on your traps.
