I love scouring for the best Prime Day deals, so it brings me great joy to share these awesome deals with you. I also love making sure I have the best fitness tracker, and I’ve tested enough of them now that I think I know what to look for. 

You want a comfortable strap, a bright, vibrant screen, and a range of fitness types. That's why the Amazfit Band 7 which is down to just $39 at Amazon, is such a great deal. Despite the bargain price, it can track my nights dancing with friends through to resistance training at the gym,
