Yeah, I use the powerlifting model of hip lower than knee. Most of my lifters go much deeper than that though.
Nick and Max squat like Olympic lifters, high bar, narrow stance, deep.
Those that squat like powerlifters, low bar, wide stance, shallow are the ones who have trouble at my comps. That style is more suited to guys wearing belts/suits/wraps, they rely on the equipment.
Nick and Max rely on their strength lol.
I dont have many clients who squat PL style, although I have no issue with it. I let lifters use whatever style they are more comfortable with.
But I explain, that if you are going to squat raw and deep, you cant do better than squat OS. Max is only 5kg short of 2.5 x bodyweight using that style.
Very little judging required when PTC lifters are competing at my comps Adrian.
I still have your T Shirt here as well. I need a DB rack, will contact you shortly
