Scales are a dime a dozen, but things like body fat, blood pressure and BMI -- things most experts will tell you matter more than just sheer weight -- are harder to measure.

Unless, of course, you belong to Lifestyle Family Fitness.

Spend about five minutes on the LifeCenter kiosk and each of these critical metrics (and more) will be updated, so you never have to wonder if you are making progress. You’ll know which activities produced the best results for your individual body type, and that will help you maximize your results over time.

Plus, you can have a little fun with it by challenging your workout partner to a fitness challenge to see who can lose the most body fat (or whatever).

Take that, Facebook.
