The new Venu 3 from Garmin can calculate an estimation of your fitness age by taking into account your age, resting heart rate, and body fat percentage (taken from a smart scale) or BMI number. From there, you'll get advice on how to improve your fitness and lower that statistic. There's also something called Body Battery Energy Monitoring, which tracks your body's energy levels throughout the day in a bid to help you find the best times for activity and rest. This could be useful to working out when it is best to go to the gym and when you should stay home.

This data is presented on a circular AMOLED touchscreen display inside a 41mm or 45mm case, and you can select various colors, including black, gray, gold, silver, whitestone, and slate, with a strap to match.
