Guys, conditioning your hands, feet, shins, scrotum, arm pits, or anywhere else you feel needs tough, ugly callused skin, is NOT that important, NOT to the EXTENT showed here, ok?
Makiwara training was desgined to strengthen the wrist, calluses were a byproduct/side effect of the training, and they can be removed/eliminated by anyone who wants to, WITHOUT effecting the conditioning.
People have ****ed up hands because they WANT TO.
You CAN'T condition your body to take blows on the vital areas, if you could PRO boxers and Fighters that make millions would have done it long time ago, ok?
The only conditioning you need is what you get from you bag work, sparring and makiwara ( if you do makiwara).
Anything else is for ego purposes, ok?
