Yup, can confirm. Had forearm pain for years (started in the wrists when I started using a laptop at school), did the whole round of ergonomic keyboards, joystick-mouse, etc. Eventually went to a personal trainer who had me try pushups, couldn't do them because of wrist pain. He then made me do deadlifts, which were tricky at first because my grip strength wasn't great, but after just a few sessions it improved markedly, and with it, my wrist/forearm pain. Long-term relief, too. I'm only now (seven, eight years later?) starting to feel it again.
