Losing steam on your New Year's fitness resolutions? A fitness tracker can help motivate you to stay on track, and one of our favorites is on sale at Amazon today.

The Fitbit Inspire HR, which earned an excellent rating in PCMag's review and our Editors' Choice award, is already a good deal at $99.95, but you can grab one right now for just $69.95, a 30 percent discount. This is an Amazon Deal of the Day, so don't wait until tomorrow, or the price will go up. It comes in black, lilac, and white color options, and all are on sale.

Unlike the basic Fitbit Inspire fitness tracker, the HR version offers 24/7 heart rate monitoring, allowing it to identify heart rate zones, so you can see whether you're in fat burn, cardio, or peak zone during your workout. It also tracks your steps, distance, active minutes, calories burned, and sleep stages, including how long you're in REM, light, and deep sleep throughout the night.

"The Fitbit Inspire HR provides you with all the basic fitness features you need in a sleek form factor that's easy to use and can be worn on a daily basis," we wrote in our review. "It tracks workouts accurately and offers many of the same functions as more expensive trackers."

It lasts for up to five days on a charge, and fully charges back up in just two hours. It's water resistant to 50 meters, so you can wear it in the shower or a pool without worry.

Don't miss this chance to snag a Fitbit Inspire HR for just $69.95.
