It's normal to feel sore hands after two hours of fitness. On the one hand, it shows that you don't exercise much at ordinary times. When you suddenly do strenuous exercise, your muscles will release a lot of lactic acid because of temporary anaerobic breathing, so you will feel sore all over. Generally speaking, this kind of pain will last for a week or so, and then disappear, but I advise you not to stop. As long as you persist, it won't happen after a while. I used to study physical education, and I know something about it. I hope it helps you.
