Re: the Mens' Health argument:
I have worked with a trainer for about a year and a half up until recently. He is kickass at designing workouts in such a way that incorporates much more than just the one muscle group that is usually targeted by a certain lift, thus working more muscles and burning more calories in the same amt of time.
One thing that I noticed over the last yr or so working with him is that many of the new things that we would try out would appear on my twitter or Flipboard timeline a month or two later from Mens' Health as the new thing to try. Lifts and methods that were very successful for me.
So, personal perspective speaking only, Mens' Health seems to have something figured out as far as workouts that help me personally.
That said, I have never pulled a workout from Mens' Health directly.
