Re: Concrete Ukemi
A couple of points.
First of all that is what mats are for - we don't want or need to abuse our body on concrete.
That said - the occasional role on grass, concrete, sand whatever highlights what we can ignore on the mats.
When you do role on concrete I got to ask - do you where street clothes. I mean there is the world of difference between dogi and leather jacket and boots. What worries me most about mai ukemi are the edges of my feet - but then I would never consider doing roles on concrete without shoes.
