Heart Rate Log For Today’s Exercise
Well, today I wore my Polar heart rate watch to the gym, and downloaded this nice log of my 45 minute workout. I did 30 minutes on the treadmill, alternating a quarter mile at a four mile per hour pace, and a quarter mile of running at a five mile per hour pace. I then did 15 minutes on the elliptical trainer at a mostly easy pace.
I uploaded the data from my watch to the computer, exported it as a text file, and then wrote a simple little gnuplot script to graph it and dump it as a png file.
