I honestly believe after a couple years on and off that my wrists are the problem. Every heavy box I used to lift at work, if my hand had to be bent a little, I would feel the stress on my carpals, A LOT. Dimensions: the smallest part of my wrist (ulna + radius), is nearly 5.9 inches (15 cm) around and looking from above pronated view, the width is almost but not quite 2 inches (5.1 cm) Examples There are many times when I feel I could do farmer's carry for longer for example, if it weren't for my hands and wrist begging to let go. Last week I was hitting pads and bags with 10 oz gloves, and I could not do very much, when my forearm strikes the arm of a bigger guy I end up with pain shooting across my entire forearm, it's embarrassing and painful. Any suggestions. There are small women with larger, more stable forearms than me.
