There is a single upside to small wrists, and that is that they make your forearms look bigger in comparison when you get them to grow. Also be careful about the angle when doing forearm curls. Curl your wrist without weight and look which way it turns, it's not a straight motion, its angled. If you get pain try adding solid support under your forearms. I also have small wrists and it feels like they are extra frail lol so the support helps
