Two things stuck out this week. One an experience; one was a food investigations video clip from the BBC. Both had to do with bodyweight right here at summer’s opening weekend, wouldn’t you know it?
Let’s start with the experience: I took my first hill hike wearing a 12-pound weight vest a few days ago. That’s not much weight, a nudge under 10% of bodyweight, but the difference in effort output was significant. There are no flats on this initial one-mile trial; I was surprised to discover both the downhill and the uphill were noticeably harder.
More effort required was to be expected, of course, but what was notable was that both knees and ankles hurt during a walk that I’ve become fairly accustomed to doing without even dying at the top.
The second vest work was flat and measured, on a track at the local college, two miles in 38 minutes. The extra 12 pounds adds a couple minutes per mile, maybe a bit more, but more than time, that weight added mental effort. Pretty much every trip by the gate incurred thoughts of bagging it; carrying extra weight is hard work, and a major strain on the back.
It struck me how much of a toll on the body carrying an extra 10-15 pounds of bodyfat can be. Do your back, hips, knees and ankles hurt all the time? Are you exhausted after a day’s activity? These weight vests are too pricey to pick one up to test the theory, so you’ll have to just drop 10 pounds to see what it does for you.
One incident happened during the college workout that was kinda funny. The Santa Cruz County Sheriff’s outpost sits around the back turn of the track. On my third trip ‘round, heading right toward the modulars, a deputy drove up and parked, but instead of heading in to the station, she stopped and eyed me pretty closely. Aware I might have looked like a suicide bomber wearing that vest, I started pumping my arms pretty good to show her I was really taking the workout seriously, really training hard. Eventually she went inside, leaving me to re-consider my idea of a daily weight vest hike to the post office to get the mail. Probably make a few people a little nervous.
Here’s an introduction to weight vest training; Xvest, Smartvest and WeightVest are the three manufacturers our forum members have sampled so far.
An alternative to weight vest work is sled dragging. It’s similar, but different in how the weight is carried, and how mobile you’ll feel. Sleds are also about as expensive as vests, although you can rig your own dragging implement, or you can even make yourself a sled. Byron made me a snazzy one, and offered to write up the instructions, so I’ll get after him about doing that next week.
When we start talking weight—fat weight, not vest weight—many of you probably share my thoughts about metabolism. We’re getting older, our metabolism is dropping and that’s why we can’t lose fat the same way we used to. Could be, but maybe it’s something else indeed.
In this BBC video clip, researchers compared the metabolism of two women to determine if a fast metabolism helped one of the women stay slim, and a sluggish metabolism caused the other to retain fat. As it turned out, surprisingly, the heavier woman burned more calories at rest than the thinner one. It takes more work to maintain a heavier body.
Next they snuck a look at exactly how many calories each woman ate during a test day. You know what they found? Yep, you guessed it. Even though both women—two friends who spent a lot of time together, eating most likely—thought the thinner woman ate more than the heavier, in fact she ate about half that of her weight-challenged friend.
That reminded me of a real eye-opener during a weight-loss IDEA seminar by Len Kravitz. One of his examples was a comparison of beef cuts, and the steak I favored—a boneless ribeye—was about 1,100 calories for a steak that looked kinda normal size. That was the last time I ate a whole steak; a third is about it these days.
From the BBC website, here’s where you’ll find the rest of The Truth about Food video clips.
This weight thing, it could just be a case of decreasing activity. We get a little older, maybe we start sitting things out just a touch more often. Over the course of a week or a month, that can mean the difference between a pound removed or a pound saved.
I think I’ll go take a walk and think about this.
