Right and Left

There used to be a saying, that Karate trained our right hand and right foot far more than the left side.
This is especially true for me who practice Kata more often.

A 'simple' Ura-Mawashi-Geri can be executed with my right leg. But when I kick with my left leg, the kick is just moving in a wrong direction. Instead of hitting in, it is just brushing up and down against the target.

I remember in a forum that i visit last time, one (or some?) people said that, they purposely practice the Kata the other way round, so that they can practice their left side as well.

Today's 一言：Left side practice?
