they could be not landing their knuckles straight into the bag but connected at an angle which is not good for your hands and wrist to deal with the force.
They might be hitting the bag wrong, I've heard of people having that problem loads of times.
Most probley no hand wraps hitting the bag wrong and just tryna be stong when thats not what it is for
Whenever i'm working the heavy bag i see a few people hurting their hands or wrists when punching the bag although their wearing a heavy duty glove... why is that so? also would hitting a punching bag with a glove damage your hand? and how much would it damage?
