Thanks for the replies, everyone!
My bench press fails at the bottom position.
Regarding what I do for assistance exercises, I should prolly say that I'm not focused 100% on powerlifting. But I'm looking for any new ideas to increase my bench press. So I'm not doing any of the mentioned accessory exercises, but I'd like to start.
But I'm not yet sure how to do them, I'll have to check the Westside site.
I've been doing close grip bench press, and wide overhand rows, for exercises in the same plane as bench.
Plus I don't have dynamic/maximal effort type split, nor does my gym have a power rack.
Thanks!
