Serious ah? Got ask them from which club? Shouldn't do that lah,
it's bad for your shins. They think it's hardcore but it's actually
doing them harm not good.
In olden days the thais use soft banana tree trunks before there
was modern equipment, but nobody does that nowadays, we just use
bags to condition.
Don't use things like coke bottles or rolling pins also, it's bad
for your shins.
