You’re probably about 4” high to get a good lift in most powerlifting feds.
Squat moved pretty snappy and it was a nice gym lift man.
Also, squeeze your glutes hard as you can before you begin the descent - this will pull your hips forward to lock you out into a better position under the bar before you descend, as well as further activate the strongest muscle in your body so it’s maximally engaged from start to finish.
Also also, nice beard
Unless you are trying to add maximum poundage to your overhead lifts, get the neoprene sleeves. They’re much better to keep on through training and provide passive support & warmth. Multiply sleeves can’t usually be left on too long and should be thought of more like mild knee wraps for a lift.
If you want to do a powerlifting meet your only option is a 4” belt, but 10mm will be easier to get down with than 13mm if your current is a 13. I wear my 10mm 4” belt an inch or two higher in the front on deadlift compared to squats. If you don’t care about powerlifting meets, the Cerberus deadlift belt is kinda perfect. Spud makes some great ones too. Gives that tension to brace against without getting in the way.
