Well, this is a tough one to answer. As far as circuit training goes, it’s a hell of a circuit workout. Judging by the cast, the exercises works, but is it a workout that will last beyond the movies bravado? My answer is no. This is just hyped exercise fad from the movie although the workout and the people teaching it are legit. The guys over there at Gym Jones are skilled trainers and some of the best at it, but the flash of this 300 workout, will be short lived. As soon a the movie fades, so will the workout, but not the ideals. This is a bodyweight and drill based workout and that is a fundamental, not a fad. I just wish it wasn’t called the 300 workout, but guess what, this workout will resurface. It will return as either the Miami Beach Workout, the Ironman Workout, the new Indiana Jones Workout, or the Rocky #23 Workout. Whatever the reincarnation is called, it will be a great workout masked as a Hollywood quick fix.
