I have a reluctance to respond to this, as I think you may do some serious damage to yourself. As Sifu mentioned, there is a real chance for injury.
Also, I question your motive…if you are a TMA practitioner and your school can’t / won’t teach these methods, then that?s one thing to make an educated study and pursue from there until you find an appropriate instructor. If you just want to be a “bad ass” or get into combat sports, this is not the avenue you want to go down.
There are many ways to condition and harden bone and toughen yourself. There is ?hard? and ?soft? styles as which can best be described as:
Soft: Less tissue damage at training, but takes longer. (Buagua, Tai Chi)
Hard: More strenuous training, more tissue damage, however, effects can be realized in a (respectively) shorter time. (think Shotokan, Hsing I)
As Sifu and Texas mentioned, you can hit things, and roll bottles and bats down your forearms and legs. Allow me to give a more structured regimen (this is the part where I take no responsibility if you injure yourself, blah, blah blah?):
Get a table about waist height. Cinder blocks will do, just make sure its stable.
Get a 70 lb. Sand Bag, preferably the long type. Wrap it in duct tape to prevent sand from spilling out if you damage it. You will need to be able to hang this somewhere as well as lay it on the table.
(By the way, be smart. Don?t ruin your ceiling or your mothers? kitchen table?)
Hit the bag with your forearms, and shins. This tends to be easier in a figure 8 pattern. For example, right ® inside, R outside, left (L) inside, L outside and repeat. 100 times each arm, every day. Same with your shins. Kick it at different parts of your shins.
Gently at first; increase how hard you hit it as you progress. You are looking for a slight bruise on either side of each arm. If it goes dark purple, you?ve done too much. This is a marathon, not a sprint. Pace yourself.
Hit the sand bag with your fists, side of each open hand and palm. Same principle applies as above.
Do this for a year, everyday. That means every single day. You are trying to build up the equivalent of a callus, so it takes a repeated effort. So on or about 3/27/08 you can re-post for phase 2.
