Know your body
Get to know your body and find out how to improve your health with the educational fitness band Charge 3. It allows you to monitor your heart, calculate burnt calories, check your sleeping habits, know your cycle and learn about the effects of physical activity on your body. The longer you wear it, the more you will find out about yourself. You can even keep it on while swimming, as Charge 3 is water resistant to 50m. It automatically recognizes the type of activity, displays smartphone notifications and calendar entries, and reminds about moving if you have been sitting too long. This lightweight aluminum band with a touchscreen lasts up to 7 days between charges.
