John’s Ramblings

Last night was our second HIT spin session. I downloaded the heart rate monitor information this morning, and here is the plot of my ticker during this workout:

The sloping line across the top is Altitude, but as you can imagine I was stationary and the garage was not rising out of the ground. A storm cell passed over the area just before the session began, so I assume we’re seeing the change in barometric pressure. Interesting, but I digress…

The first three heart-rate peaks are spin-ups… intervals where you increase cadence at specified times to specified rpm’s.

The next six (smaller) peaks are Individual Leg Training (ILT) Intervals. One foot is clipped in and pedaling, the other is unclipped and propped up out of the way. I started out with my left leg, which is definitely the weaker of the two. While I knew at the time that my perceived exertion was greater on my weaker leg, the HRM plot really shows how much harder I am working to keep the left leg going for 3 minutes.

The big blob in the center is a standing interval, 12 minutes long.

Three more sets of ILT’s follow the standing exercise (left leg first again), then a final tempo spin at 100+ rpm for 5 minutes.

One other thing I’ve noted is that I’m finishing “strong” on the standing and tempo portions. I pushed harder in the final minute of these intervals. I’m not sure if that is good, or whether it’s an indication that I’m holding a little too much in reserve, or whether I’m WAY too obsessed with data.

I’m fatigued today, but not overly sore. I feel it most in the muscles in my hips.

No mileage, but 1,100 calories.  w00t.
