Everyone is against it, but I'm gonna start using straps from now on.
I think I have a terrible "build" for mixed grip, the arm that's suppinated sticks out a lot for me, so deadlifting with a mixed grip is extremely strange to me - if I want to make enough space so that the elbow of the suppinated arm doesn't get in the way of my knee, I have to move it like 2 or 3 inches further out than the other arm, so I don't think it's very safe for me. I've been trying the hook grip and my thumbs are cracking all the time, going numb, and it really hurts, the pain on the thumb joint is just really bad, I sometimes have to jump up and down like a girl, after finishing a set of rows. I'm probably not gonna bother with getting used to it anymore and use straps instead.
So I'll be using straps and spend extra time doing static double overhand holds.
If I was to compete once though, I guess I would have to get a bit more used to the hook grip, but so far I just don't find it worth it, I'm really afraid about doing something to my thumbs.
