I've had issues with my wrists for a long time. My wrists have always been small (I can easily wrap my other hand around my wrists and touch my thumb to my middle finger with room to spare).
Usually it's not too big of a deal, as I just avoid doing pushups on my palms, but I've been applying for some jobs that have PT requirements that include pushups throughout their academies and I'm trying to find a way to hopefully remedy the situation.
Is there anything I can do to strengthen my wrists so that pushing off from my palms repeatedly doesn't cause pain? I actually really hurt one of my wrists a few years back during a CPR class where I was performing chest compressions for about 10 minutes straight. I could barely move my wrist for a couple months after that.
