This woman wanted to test her fitbit by wearing it during sex

For anyone who isn't aware of what a Fitbit is, it's a heart-monitoring device you wear around you wrist while you exercise so you can track if you are losing weight and burning calories. 

But it turns out, it can be used for more than just hitting the gym. One woman decided to wear it while having sex with her partner so track her heart rate. 

This brave soul shared the information about her 8 minute session on Imgur and it has since gone viral with many people saying they are going to try the same thing. 

The gadget recorded the peaks and drops of different positions and climax during sex. An average of 109 beats per minute were recorded and that figure is within the range for burning fat. 

The woman who posted the graph described herself as a 'fit lady' and said she has a resting heart rate of 60bpm and that her heartrate is slower when she is at the gym than shown in this graph.

The graph has been viewed over 1.7 million times and people have began seriously analysing it in the comments section below. 

“Everyone focuses on the time,” noveltysin wrote on Reddit. “I lose track of it. Time stops. I'm happy.”
