Secret codes and rationalizations
Today I was supposed to do over/under intervals. Carmichael describes them as dividing intervals into sections of 92-94% of your maximum sustainable heart rate with other sections at full-tilt 100% plus.
In the book the description reads:
60-90 min EM with 3x8 min
OU (3U,10) (6 min RBI)
Which was making me crazy. What does that "10" mean? After entirely too long — I mean days — I finely realized it wasn't "one-zero," it was "one-over." So: Three minutes at 92%, One at "crazy," then repeat. Do that three times. So I did. You can really see the "crazy" parts in the graph.
The graph ends up interesting because the heart rate lags behind the work done, i.e. it takes a moment to ramp up, then a bit to wind down. That must be why people spend big bucks on power meters.
Is it time to start the rationalization machine? Is a power meter really that expensive, considering how much they do, and how cool they are? And because I don't go to Starbucks and buy a fancy coffee drink every day I'm in effect saving all that money that could go to a device that would only improve my health, making me a happier person, which would benefit every single person I come in contact with.
