Fitness log, 8/8/10

8 08 2010

Lately, other than brief interruptions when I travel (and even on my trip to China, I made mostly responsible food choices and hit the gym a couple of times), I’ve been very consistent with both my diet and exercise. About a month ago, I started Jim Wendler’s 5-3-1 program, and I’ve been very pleased with the results so far. In addition to that, I’ve increased my overall activity level: taking the (7 flights of) stairs at work, walking more (a half hour each way to the gym yesterday), with the occasional bike ride, jumping rope, and sprinting. My weight is dropping consistently, and I think I’m on track to hit 200 by the end of August.

I noticed something disturbing today. According to my Tanita scale, I currently weigh 207.5 with 27% body fat. I’ve said before that I think that’s considerably higher than what I’m really at, but taken at face value, that means I have about 150 pounds of lean body mass. Back in January when I first started this, I was 232.5 at 31% body fat. That’s a bit over 160 pounds of lean body mass. So assuming that the scale is at least relatively accurate, that means I’ve lost 10 pounds of muscle and 15 pounds of fat.

I’d like to write off the muscle loss as inaccuracy of the scale, but the truth is, my training logs show that I AM moving less weight than I used to at the gym, and my muscles seem to be a bit smaller. Really, this is no surprise. I went through a period where I was horribly inconsistent with my weight training, and then in April, I suspended it completely to focus on preparing for Ragnar. As I said a few posts ago, I think that running is terrible for fat loss precisely because it does nothing to preserve muscle, and my experience seems to confirm this.

Based on my current numbers, to get to my ultimate goal of 10% body fat, assuming that I can hold onto the lean body mass I have now, I’ll have to drop down to under 170 pounds. Ugh. However, I estimate that my scale reports at least 5% higher than what it really is, and if I stay on track I’ll probably be adding some muscle back on, so it may be more like 180-190. That’s not so far off.

My legs would beg to differ… however it certainly does nothing for the muscle anywhere else on your body.

Nice job on the weight loss though.

I think that some people tend to do better with it than others (and certainly, I’m a big fan of sprinting), but I think that the majority of people who run for fat loss don’t constantly push themselves (and really, there’s a limit to how far they can go with that) so they eventually hit diminishing returns.

At GDC, I’d be happy to compare the leg muscles that result from squatting and deadlifting vs. running! 😉
