Well, I haven't varied the routine much at all since I was 14 and it still feels intensive. It is an exhausting 3-4 minutes. I don't put on extra muscle, I maintain what I have. So I look much stronger than I am.
Fair enough. Thanks for the perspective. just posting about this got me going building 'ninja' obstacles again in the garage, nothing crazy more borderline rock climbing similarity, but still something.
