FitBit Charge HR - Early Birthday Present

As I mentioned in yesterdays Birthday Wish post, I am the proud new owner of a FitBit Charge HR. I’ve been using the FitBit Flex for almost a year and finally got to the point where I felt as though I was outgrowing it and wanted something with a built in heart rate monitor.

As you are probably aware, on July 15th there was a bit of a sales war going on online. Amazon was promoting Prime Day and Walmart battled back with a massive series of rollbacks on their website. Having a hunch that the FitBit would go on sale, I got the green light from my wife to buy one at a discounted price.

I missed the better deal at Walmart (I was on the treadmill and couldn’t check-out because I didn’t have my credit card handy) but did manage to get one through Amazon. With Prime Shipping, I had my new fitness tracker a couple of days later and was eager to put it to use.

Over the weekend I had the opportunity to mess around with the device and see just how it would react to my day to day activities. While I didn’t formally exercise, I did mow the lawn and set the tracker up to monitor my heart rate. Seeing the graph was nice but because the activity was kind of random, it didn’t tell me a whole lot other than my peak and average heart rate.

On Monday I wore it during a gym session and the graphs in that case were far more interesting. I don’t particularly find heart rate monitors useful during strength training, so I only switched on activity mode my two cardio sessions.

The first was a straight up run on the treadmill. I spent 15 minutes running at a pace of 5.5mph with a 3 minute cool-down at the end with steady reduction in speed (I forgot to switch the tracker off right away which is why it is reporting longer).

More interesting was my second cardio session. I set the treadmill up for interval training with a slow speed of 4.6 mph and a fast speed of 6.2mph. I did a 30 minute cycle of 2 minutes slow followed by 1 minute fast. As you can see in the graph, the more time I spent on the treadmill the more fatigued I became and the higher my heart rate climbed during peak speed.

While I haven’t compared the two, I also happen to have an older Polar Heart Rate Monitor Chest Strap from when I was doing Focus T25. I’m curious how the two devices stack up against one another in terms of accuracy. I assume the Polar will be more responsive due to the way it functions but as long as the FitBit is moderately accurate, I’ll be happy.
