I think you're over thinking the pull up. I tend to grab the bar and pull myself up to it until the top of my chest hits the bar. Works pretty well for me. Dad needs a new lifting belt because he lost his poverty golds gym one. Gonna give him my inzer single prong, think it's 10mm can't remember. Obviously i'll need a new belt, considering a lever because its easier for speed work, but it seems like hassle to change the lever position so I can do weighted pull ups with it. Where to kop new belt? I'm very happy with my inzer, but i'm willing to try a different company, considering EFS because I'm poverty and inzer has increased the price of there belts by like $20 this year, which I would say is slightly past my budget constraint, but belts seem to be rather inelastic because I'm still considering kopping.
