There are many different activity trackers available out there in the market these days, but many of them can cost upwards of $150 or more. This is where it's a good idea to look at options for older models as they can sometimes be a bit cheaper than current devices. For example, right now you can currently pick up the Fitbit Flex activity tracker on sale for just $66.99, which is nearly half the price of the Fitbit Charge, the next model up. What's more, is that the deal has the Fitbit Flex on sale and available in three different colors which include, Black, Pink, or Teal.
The Fitbit Flex activity tracker is capable of the more basic activities like step counting and keeping track of how many calories you have burned in a day, and although it doesn't have a small LCD display to show you your stats on the device itself, it does connect up easily to the Fitbit app on your smartphone so you can view all your exercise details there. It does include LED indicator lights to show you your progress throughout the day with each light being representative of 20% of your progress. It's water, sweat, and rain resistant, and you won't have to worry about recharging for 5-7 days.
