Whether you’re always on the move or need a little motivation, the Garmin Vivofit 24/7 activity band helps you monitor your fitness and develop a healthy lifestyle. What sets this tracker apart is the notifications that alert you when you’ve been idle for too long and it assigns a personalized goal each day. Other trackers like the Fitbit Charge do not have this option. Grab it on sale for $79.99 at Sports Authority. It’s normally $149.99 and the best price you’ll find elsewhere is $99.99.
