Useful thread!I picked up a few good pointers here.Just a question guys…If you’re doing board presses or rack lockouts as a supplemental lift and not your main exercise what rep-range would be good for them?
As an accessory I would stay in the 5 rep range. To the OP without seeing your bench I would say you need to stay tight and get more lats. Your shoulders and chest should not really come into play in a powerlifting bench. If you are feeling it in your chest and shoulders that means you are flaring and not using your lats.
