just hitting the bad with no Skill is a pretty good workout wich seems like thats all they want at the local gym in my town all they have is this poor a** kickboxing but all it is, is for old people or woman who want a workout i asked the instructor if he was actually gonna teach us some skills and he says its not his job and thats not what the class is for so i decided to just train myself because what good is it for him to teach me how to poorly hit the punching bag when i can just go out and purchase a video that tells me more about boxing then this guy would ever know
