On conditioning people have different views and use different implements. Some over-condition looking for the magic bullet and hurt themselves for the long run.
Personally, this is what I do:
1. I use the 'iron arm' _ see here http://uechiryu-karate.com/products_ironarm.htm_
have used it for many years.
I keep it down the basement on a table next to where my shoes are, so I must 'go by it' at least twice a day as I put on my shoes and take them off coming back home. Next to the iron arm I have a heavy rolling pin_ http://www.amazon.com/Crestware-18-Inch ... B00857WJ68
I don't go back up the stairs unless I use the iron arm to tap shins/forearms, etc. as you see in the link on the product.
Then I use the rolling pin up and down the shins pressing down hard to desensitize the nerve endings on the shins.
2. When at the dojo, we use similar implements for the tapping and rolling….then we strike a heavy bag which is placed standing on the floor with students taking turns holding it and kicking it…then we finish with two men conditioning drills where we kick and absorb kicks up and down the inside/outside of the legs…bone on bone.
We then perform the arm rubbing and pounding along the same idea with a partner plus striking the 'Bob'_
We do have 'wall makiwara' to practice the 'iron palm' and padding attached to the bottom of the wall to practice toe kicks, as well as tapping each other's legs/shins with toes.
Strong toes are a Uechi icon and very effective in front kicks even with shoes on.
