havent used it in years. I got my core silly strong and if my abs are a weak point then so be it. ill keep training them to catch up. I recently had to focus on my lower abs as I was improving my deadlift.
You need to know your body and limitations though. I train my core a lot and have done so for years.
I dont use wraps, gloves, straps and im barefoot half the time when i do military presses, squats, etc etc.
dont just jump into this get hurt then blame me. this is not the way to go for most people IMO
