(My previous post was for yesterday)

I weigh 173. I am trying a new routine where I run for 15 seconds, and only walk 45 seconds per interval. I am running now and I have stopped off at McDonalds for a short rest and water. This first mile I set a new personal record of a 11:45 minute mile. I could of ran a bit faster, but I am happy that I did not. Even though I still have energy left, my heart rate averaged 158. I have had this higher. But my peak was 176 again. When I am getting near my goal, I will watch closely my heart rate and adjust the running part of the interval accordingly. My next goal is a 11:30 mile, but this will take time.

Here are my exercise stats. I walked and ran 2.5 miles. I have burned 289 calories. This gives me a target of 2789 calories. I began pacing myself toward the end by heart rate. On the second leg, my average heart rate was 163, with a peak of 175 bpm. All stats tell me I could of not had a better workout. I had arrived exhausted compared to the first leg.

BTW There is a value on my watch that in one number provides me the aerobic effect of an exercise on my cardio system. It is surprisingly accurate. I can have excellent stats, but if I finish where I feel that I can do more, this value is lower. If I have stats that are not as good, but I arrive completely exhausted, this value shows me that I had a better workout. How does the watch know this? It is measuring the variability of the timing between heart beats. The more the body is stressed, this value increases. Amazing technology. What a toy!
