Third Sign, Technology Hook

My wife informs me,

”the heart rate monitor is an essential tool in maintaining an aerobic workout.”


Which I kind of understand. Aerobic workouts are entirely defined by maintaining your heart rate in a target zone for a period of time. This is stuff we have know since Jane Fonda sold VHS tapes.

I am expecting a wristwatch that takes your pulse. Maximum logic might include 2 beeps if your heart rate is too high, 1 for too low, not working hard enough. I seriously underestimated.

This is the most insidious sign so far. Cue the "Imperial March" for this one.

The Sensor


It comes with a sensor. A wireless data transmitting device. Say it with me, Sensor.

See, now I have the attention of all my technolusting, Gizmodo and Engadget reading IT brethren. Sensor? How does that work? Well, it gets strapped to your chest so it can sense heart beats and transmit an RF signal. It runs off a watch battery both to transmit and apparently to sense the heart. The Velcro® connector must be wetted for proper function, so they must be sending some current across the length of the strap.

The signal is picked up by the wrist watch receiver. Apparently, taking the pulse at the wrist doesn't work very well. Maybe there is something more to this, though. The signal is also picked up by the treadmill at the studio. So the sensor feeds a vast array of fitness related equipment.

The Receiver


The receivers can be programmed to emit the aforementioned beeps I suspected according to your personal workout profile. Using software on your PC (yes, PC only, us Mac guys get screwed again) you enter your height, weight, sex and desired fitness level. Then you get emails from 1000's of horny guys from around the globe. Oh, wait that is another kind of website.

The target heart rate and length of your workout get calculated and sent to the watch (or treadmill or whatever). Yes, calculated. It knows about warming up and cooling off periods. This little watch thingy packs more power than my old Zaurus. You can also send little block pixel "backgrounds" to your watch in case you miss your old Tamagotchi.

The data is not send with a cable. It does not employ Blue Tooth® or utilize any 802.x communication. No, not IR. It uses a Sonic Modem. A what?

The Sonic Modem


Here is a low tech, low speed, completely hackersmack way to transmit data. The watch has a microphone and a piezo electric speaker. The PC must have a speaker and a microphone. You guessed it, they screech at each other just like good old analog dial up. When computers were fun. When you were sure that if you listened well and trained your ears you could understand the computer's audible language.

After your work out the data recorded by the watch (treadmill) can be uploaded to the Polar website. Why I would ever want to post my poor performance to everyone on the planet I am not sure.

The Invitation


So the insidious part comes via invitation. Her personal trainer invited me to come in and see the equipment. I can check out all the sensors transmitting, fitness equipment recording, internet uploading and get a free Personal Fitness Report.

A what? Well, they have a machine that will measure my lean mass as a percentage of my overall mass combined with a short run on the treadmill with the sensor we can determine the exact amount of pure flab. Wow. I was still doing the "pinch test!" Boy, am I out of the loop. Of course with all this applied technology they can upload to the internet and all of you can know just how fat I have become. Given the new fame of my fatness I will probably be motivated to work it off at the studio. "Feel the power of the Dark Side!"
