Wore one for years when i was powerlifting.
Always prefered the single-prong. Favorite belt was my single prong, grey suede, 10mm Inzer. Took a while to break in... Prolly 6 months. Looking back I'd go with a lever belt instead of the prong. In prison i started with a double prong and hated it. Went to single soon as i could (sold tons of Inzer belts when i got outta prison. Found the 13mm wayyy to stiff. Can't see anybody under 270lbs or squating 700+ needing the 13mm belts).
I find the conventional belts worthless and just for show. Too thin, too narrow, too flexible. Belts have a purpose. They're not gonna keep your waist small if used properly. In fact they do the opposite. You actually push out against the belt to stabilize your spine. Thus your waist will expand.
While powerlifting, my waist expanded to 41"+ while still rock hard (wasnt my liver, since i was on legit hrt and zero booze or any other liver enlarging shit... And no insulin. No nothing.).
Pl belts are great for squat, DL, overhead presss, & even bench press, especially if you have somebody to pull the buckle down below your belly button after youre laid back and arched. I see guys doing pulldowns with a belt on andnjust shake my head.
