I apologise in advance for my croaky voice and intermittent coughing during this interview. I had just returned from a holiday in Mexico. I think seven cheat days combined with jet lag didn’t really help my immune system. Luckily for you, I let Keith do most of the talking.

Enjoy!

    Another great interview Lawrence, it’s always great to here different points of view discussed, and also the same views as other people in the HIT community, but from a different angle or perspective.

    Looking forward to your next interview with Keith, and also Doug McGuff.

    Keep up the great work Lawrence, I find these interviews both thought provoking and invaluable.

    Regards Mal

    Great episode.

    I had a question directed at Keith.

    When you do multiple sets, do you treat it like a circuit or do you go straight to the second set? That is, do you do the whole routine first and then come back and do additional sets, or do you just momentarily rest after the first set and proceed right to the second set of a given exercise?

    Thanks.

  • Slim,
    As you might expect, the answer varies. And, too, we need to define “circuit”. For instance, most of my clients’ workouts are set in a push/pull combo of 2 exercises done back-to-back. For instance, a chest press of some sort followed by a row of some sort. We would perform 2 sets of this combo, back-to-back, with very little rest between exercises, to “failure” in each exercise. Then, we’d move on to another push/pull combo — maybe a lower body drive/hinge combo (leg press / RDL, for instance). Generally, we can squeeze in 3 such combos within a 30 minute time frame, hitting the full body with push/pull compound movements. This is just the basic template. Of course, client goals, recovery ability, prior training history, injury….all of this must be taken into account. Thus, my reliance upon the Five Ts (http://ancestralmomentum.com/2012/09/the-five-ts/) in determining one’s (including my own) programming.
