Is it beneficial to pause on some sets of benching at the bottom, relax the triceps (a bit, not totally) then try to “explode”?
I experimented with this on my “speed” day, after I read something about how pausing on the bottom and relaxing (a bit, like maybe 50%) helps improve “explosivity”. Does this make sense? Or should I just do them regularly?
No, not if you are working on power. You never want to pause on the bottom when traing the bench for speed. You want to lower the bar slowly until you get about 2 inches from the chest and then let the bar accelerate to elicit a stretch reflex.
One of the things Dr Tom McLaughlin cautioned in his bimechanics book, “Bench Press More Now”, is that you want to perform the bench with a touch and go in training to develop the stretch reflex.
