Anyone who wants to take better care of themselves will be able to make good use of an activity and sleep tracker. Depending on the specific designs and features of the tracker that you choose, you can electronically monitor the levels of sleep and activity that your body is getting. Picking the one that’s suitable for your specific fitness needs can really help if you’re trying to get in better shape.

The Fitmotion Wearable Activity Tracker and Sleep Monitor Fitness Wristband Watch is a great option for 24/7 monitoring. It’s small, lightweight, simple, and elegant-looking enough to wear all the time, with whatever outfit you have on (from business attire to gym clothes). Purchase comes with a long-lasting (4 months) CR3032 battery that’s easily replaceable with the included Quick Change Battery Tool. Its adjustable 6.25” to 9” Sport Flex Armband Bracelet allows it to adjust to virtually any adult wrist size. It’s also waterproof, so you can even wear it in the shower. In order to monitor its fitness readings, it uses Bluetooth to sync with the Fitmotion Tracker App that can be installed in either an Android or an Apple smart phone.

A more popular option is the Fitbit One Wireless Activity Plus Sleep Tracker, Black. Those familiar with the Fitbit app already have an idea of how this device can track steps, distances travelled, stairs climbed, and overall calories burned. It also features a silent alarm that wakes you (and only you) up at the right time. You can check your numbers wirelessly via computer or one of the 150 smart phones that it’s compatible with, allowing you to set goals, earn badges, and check your overall progress.

There’s also the Polar Loop Activity Tracker and Sleep Monitor, Black. Apart from monitoring your progress via the free Polar Flow app and training community, this tracker can give you live feedback through its 85 LED data display. It’s fully waterproof, so you can even use it for swimming. The rechargeable battery is good for up to five days of continuous use, which means that you only need to take it off for charging once every five days.

Wearing a reliable activity and sleep tracker is a great motivational tool for both health-conscious amateurs and elite health buffs/athletes alike. Think of these devices as personal fitness coaches that you can wear on your wrist and consult whenever you need to.
