Well, I'm currently in week 3 of this Pfitz 12-week training cycle and so far, so good - at least on the health front. Fitness (and hopefully, speed) will come as I get further into my program I'm sure.
While I've been pretty successful in getting in the early morning runs, I haven't been as successful in taking steps to shed the weight I sought to lose when I started a couple of weeks back. Hovering somewhere between 183-185 lbs (@ 12-13% BF), I can definitely feel it at the tail-end of my runs when it feels like I've been running around with a weighted vest.
I suppose I figured the weight would magically disappear as the mileage increased, but I can't rely on that this time around. So I'm going to take some important - but not impossible - measures to change up my diet, throwing out most products that I've cavalierly consumed in the past.
This will entail more cooking with less eating out, more 'raw' snacks (fruit, almonds, etc) and less soda/high fructose syrup type drinks. To prevent myself from going completely batty, I'll leave myself open to the occasional indulgence. And I'll probably still leave energy bars in there for convenience, but will scrutinize nutritional content a little more. It's all about eating sensibly...not restricting myself to some diet, per se.
And coffee will still remain a staple. No way I'm giving that up.
