this topic came up a few weeks ago. the guys who wear straps will argue for them. the guys who don't will argue against them
as someone who used to use accessories for a short time i am 100% against using them. they will increase imbalances which are going to cause you problems. you aren't improving your raw grip, you are causing it to lag. i am a proponent of raw lifting with proper form. no belts, no straps, no gloves, no nothing. when you get to mobster's level you can do what you want to set PR's or what not, but especially younger guys or recreational lifters you have zero business using any sort of accessorie!
