Hello Lena,
Thank you for the interesting insights about fitness and health you shared here: mingyuexuan.blogspot.com/2013/01/the-no-equipment-workout.html. I'm currently trying to change to a healthier lifestyle and what you shared was very helpful.
While checking other interesting resources, I came across this worrying report about a recent data breach that affected a lot of fitness apps/wearables: https://www.websiteplanet.com/blog/gethealth-leak-report/
Famous apps' brands such as Fitbit, GoogleFit, Apple HealthKit, S Health and more got their users' data leaked. That's pretty scary...
I wanted to share it with you, because the article teaches us the importance of being wary with our data while using fitness wearables. I believe it would be very useful for your readers too, should you decide to share it with them.
Best regards,
