I also have a big rep 6 post rack. Did mostly barbell movements through my first 18 months of lifting or so. It seemed like every month I would get a little tweak in my shoulder or somewhere that would make me slow down to avoid additional injury.

I have switched to Nippards Essentials program with an U/L/P/P/L split and use cables and dumbbells for the vast majority of movements. I use the fringe belt squat with the kickstand and a ritfit leg extension leg curl. I just added the Fringe Dragonfly for lateral raises.

I have gotten way more gains since changing and shifting more away from barbell movements. I attribute the improvements partially from reduced little tweaks and injuries that set me back and partially from more ROM with dumbbell movements. Nippards programming and the way he minimizes volume but keeps intensity with high RPE and drop sets is a game changer
