Hey forum,
I've been focusing on externally rotating my arms during my work sets (HBP/PE2), and as a corollary I've been strongly externally rotating during my warmups too -- incline pushups on a bar (HBP/PE1). In other words, I'm focusing on keeping the pits of my elbows facing forward, particularly at the top/straight-arm portion of the element. This doesn't hurt at all when I work on the floor, but when I grab the bar and rotate, I feel a pain on the ulnar side of my wrist, on the underside. Using this picture for reference, the pain is just above the top of the 's'.
I also feel the pain when doing my wrist stretches as part of the HS series, when doing WRS/4, and a little bit when doing my wrist pushup work (WP/PE3) .

Can anyone advise me about what's happening here? I'm interested in understanding the physiology, even if I'm not a doctor. Then, what can/should I do to alleviate this pain? I'm not particularly interested in stopping my workouts if I can avoid it, but I do understand the healing process quite well; if the only way to recover here is to stop, then I will stop. But maybe this is something that can go away with targeted stretching?
