The Amazon Prime Day [2] sale is back and better than ever. It starts on July 16 and lasts for 36 hours, so you won't want to sleep on these deals. We found so many great fitness finds on discount [3], but there's one insane item that really stands out. This superpopular Fitbit Alta HR [4] ($90, originally $150) is a seriously good price.

Rarely do you find these for less than $100, and we couldn't be more excited. The Alta HR is great for those who want something sleek, comfortable, and easy.

You can sync it up to your phone on the app or even on a computer for more in-depth reports on your daily routine. Plus, it comes in three different sizes to fit every wrist.

Do yourself a favour and treat yourself to this amazing sale. Hurry before it's too late.
