If you feel guilty over skipping the gym but had some fun between the sheets this morning, you might just have gotten in your daily workout. One Redditor noveltysin decided to wear a Fitbit during sex, and shared the graph results with the forum r/dataisbeautiful: Noveltysin tracked the eight minutes of bump and grind and showed the benefits of experimenting with positions (and the joys of a little aftershock). When she orgasms her heart rate hits 123bpm, and that’s without the 20 minutes of foreplay... Speaking about her results on Reddit, she explained: "Started after foreplay, so the preceding 20 mins are untracked. “For anyone else fixated on the "eight minutes" of sex, first of all, you've never had sex that you need to wrap up ASAP because your dorm mate is coming home soon/the pizza is almost here/the kids are about to wake up/[insert other pressing issue]. Noveltysin said her sex life is great, thank you for asking. "Everyone focuses on the time. I lose track of it. Time stops. I'm happy. Mini orgasm after the main one. Yay women parts." So ladies don’t feel guilty about leaving the gym bag at the foot of your bed… there can be other (more fun) ways to get your heart racing.
