This is my Garmin Vivofit 2, I’m using it to increase my exercise. I’m trying to hit my step target on it as often as possible, preferably at least 4 days a week. The garmin automatically changes my target based on the number of steps the previous day, it increases if I met my previous target and slightly decreases if I miss it. This is definitely something I’m using to push myself this year.
It also links into my profile on My Fitness Pal and can adjust my calorie goal based on how active I’ve been. I’m really pushing to lose weight this year (and keep it off this time!)
