I honestly love what I do, and one of the most intriguing parts is planning workouts. To me it feels like a giant Sudoku puzzle. Here's the thought process (using me as an example client):
Ok, so she's wanting to lean out for a vacation in a few weeks. So we need plyometrics to really get her heart rate up and burn calories. And she wants to tighten lower body and abs. But she said her left knee has been sore and twingey, so can't do huge knee flexion. We need to talk about emphasizing high fiber carbs, as in VEGETABLES, as the trip gets closer. And I want to check how her water intake is going. So what did we do Monday...?
Those are the things that swirl around in my mind as I'm considering what to incorporate in a workout. And then, of course, I want to do new exercises for interest, but enough "old" things so there's a sense of mastery and "I know how to do this one!"
So what do I use as resources? Anything and EVERYTHING! I watch what other trainers do at the gym. I watch exercise DVD previews and do exercise DVDs. I read books and magazines and articles. And I try to find the very best of the best.
One resource that I'm so excited about I could squeal is the show "Work Out" on Bravo. Season 2 started last night and it's taking every bit of my willpower to NOT be watching it right now. I don't always agree with what they do, or even like the training styles, but it's an insider look at the training industry and it's FASCINATING!
