Hammer

This is what I did tonight . . . . hammered. Intervals. It hurt.
20 minute warm up on the way into the park. Started the timer and heart rate monitor.

Here's what I came up with:

• 1 hr 26 min of suffering, average heart rate 167bpm
• max heart rate 190bpm
• time in muscular endurance zone = 39 minutes
• time in anaerobic = 26 minutes (Anaerobic is a technical word which literally means without air)
• time in out of breath; I'm going to die; I can't go on zone = 9 minutes.

20 minutes cool down on the way home.
Cheers.
