I don't know whether the so-called pain is dull or stinging, or nerve pain caused by physical discomfort. You can check whether there is anything wrong with the equipment, then buy protective gloves and try again. If the sitting chest pusher can adjust the weight, it should start with a small weight, because all the instruments will cause some damage to the joints, and the instruments with too much weight are likely to be unsuitable for a short time, causing local pain. If the above is not the reason, you can try the equipment in other places. If you still feel pain in your hand, you are advised to see a doctor.
