How much time and therefore how important do you find hand conditioning Before it was seen as very important and I went through a time of hitting every hard flat surface I could find. I should my calloused knuckles with pride and used to really enjoy breaking in competitions and demonstrations. However as I have got older and hopefully wiser I wonder how much is really needed. There are other ways to hit someone and hit a board vs hitting a person is different anyway. I know one Nan shaolin fella. Who had huge hands developed over years of conditioning. There was also on guy who was famous because he had conditioned only one of his hands. Weird to say the least . In the modern world of iPad, smart phones and keyboard is hand conditioning a relic of the martial way?
