(1) Rollerbar method - I heard of it several years ago that its effect is similar to certain skin cosmetics treatment in changing the skin surface. But in MA hard conditioning, its effect is to change the contour of bones. It is used to make sharp bone edge rounder, for example, on the shin bone. I agree with the effect. However, I do not carry out such training as it is too much work for me. I only hit the bones, as hitting is the main method used in hard conditioning.
(2) Sand bucket - I frankly have not heard of it. Again I speculate that it is a strength training exercise (lifting weight). Strengthening our muscles is certainly necessary for hard conditioning.
when you are healthy smack yourself with a stick. when you have concussion from sparring, you cannot have any shocks or impacts, so you roll with the stick instead, and you rub your head against a wall. the two methods are complementary with each other.
iron body is light tapping just like iron palm, it follows daoist sword smithing concepts of tempering.
gentle tapping yourself with stick or rubber hammer is a common exercise for old Chinese people, theres nothing dangerous unless you go full retard
