Over the past several years, the sophistication of tracking devices has greatly improved. Pedometers that once tracked only your steps have been replaced with watches and other wearable trackers that reveal your heart rate, calories burned and how much sleep you’re getting.

Cancer researchers have even found that their patients using Fitbit devices were more active and showed improved cognitive processing speeds than those who did not use any wearable fitness technology.

And did you know that the plastic pieces and parts that make your fitness watch tick are made from derivatives of natural gas and oil production?

So this year, why not invest in a fitness tracker that will inspire and motivate you to get up and get moving?

Here are some of the most popular fitness trackers on the market:

Fitbit Surge

Fitbit Charge 2

Fitbit Alta HR

Fitbit Ionic

Garmin Forerunner 35
