the coach is this new breed of fitness elitist who thinks he is "cutting edge" just because he doesn't have treadmills and makes his clients do hill intervals while wearing a weighted vest
seriously, get off your high horse...you are training your clients with the same techniques my uncles and grandfather used back in Europe 50 years ago
then again, coach won't acknowledge me cuz i dare to admit that i'm a "trophy trainer" while he is a "legit trainer"....
