You wear gloves to protect your hands, not the other guy or the bag.
It is easy to tear the skin on your knuckles without gloves and this can be a serious injury and hurt your training.
Pain is not the same as injury.
Your hands are easily injured which is why you wear wraps and gloves, it has nothing to do with being a tough guy.
Punching a heavy bag isn't about strengthening the knuckles. It's about throwing punches correctly and with power so you need to protect your fists from getting hurt.
U can use normal gloves,biker gloves or use a piece of cloth and wrap it in your hand or u can use a crepe bandage instead of cloth...
Gloves/clothes saves ur hand from pain
bundini is correct.
You'll still get used to the pain and avoid unneccesary injuries when you have protection over your fists.
Isn't the whole point of punching a punchbag in strengthening your knuckles?
