So I finally gave these wraps a try. I watched the video they have on elitefts about using them correctly; I wrapped them very tightly as per the instructions (had to take them off as soon as my set was over as they were borderline hurting me) and up so they would keep my hands from bending backwards.
My wrists did indeed feel more stable, but the presses weren’t completely pain free. However, since the backward bend was now out of the equation, I could actually tell what kind of tension was causing the pain.
What’s bothering my wrists isn’t the backward bend, as much as it is the pressure applied in such a way that makes my wrists bend “sideways.” To get exactly what I’m talking about, imagine holding dumbbells in the bottom position of a bench press, and have the bells slightly tilt inwards. I had that on some reps and it hurt like hell. This isn’t as pronounced with barbell bench presses, in fact it’s almost absent. I did feel it at the beginning of the last few sets where I was pretty fatigued: as I unracked the bar, I felt like I was pushing unevenly throughout my wrist, which causes the same kind of inward sideway tilting under the weight of the barbell.
So the good news is the wraps do kinda help. The bad news is I don’t know how to prevent what I just described, as it seems to just end up happening when the weight gets heavy for me and I’m fatigued.
