Do you too want to know how well you trained? Is the good feeling that you get after a work-out no longer enough? Do the statistics that friends share on Facebook after running or cycling make you curious about the impact of your own performance? Do you ask yourself, “How many kilometres have I actually walked today? Was I faster than last week, or faster than they were?” Of course, seeing your training results can be a huge incentive in keeping to your weekly work-out programme. Isn't that motivation enough? And can’t you also share your results on social media and fish for compliments and encouragement?
Sports apps like Endomondo and Strava, and sports wearables like the Fitbit, not only give you a full view of your work-out, but are sometimes so comprehensive that you feel you've got an insight into your health. All of them show the distance covered, the calories burnt and your heart rate. A Fitbit even shows how you slept. You can also add your drinking pattern and changes in weight. It gives you a sense of controlling your own health. But how long will it be before the government, businesses or your employer lay claim to these insights? And how bad is that?
