I used to always use a thumbless grip while benching.......had a few mishaps where the bar ALMOST fell out of my hands when grinding out one last hard rep, but it never did, then over time, I saw a few people and even more on tape
of todays gym idiots on video drop weight on their face/chest/ribs/hips even.......... so I simply re-taught myself if you will, to go back to my roots and stopped using a thumbless grip.........felt fine once I got used to it again.
As far as wrist wraps go, if you have bad or weak wrists use athletic tape.......the best stuff to use in my opinion.
If your wrists are OK, skip the wraps or tape.
When going extra heavy if it makes you feel better mentally tape those bad boys up, but don`t become reliant on them.................... they will make the wrists weaker and/or become a mental crutch.
