Practice outdoors

"Pratctice outdoors" Traditon is, from what I have understood, the martial arts have been practiced mainly out of doors. This makes sense on several levels, economically and tactically. On the battle field of old one would run into many obstatcles. Not only from the enemy but also the terrain. Gravel, inclines, declines, forested areas, heavy sand, and now days curbs. All of these can be a detriment or a powerful ally,  in any type of physical conflict. Ones awareness of these, can  be a tactical and strategic advantage should the need arise. Keep these in mind when practicing. Mr Miller
