7 Health and Fitness Apps for Busy BIZ Experiencess Expert advice on how to use your smartphone to reach your health goals.

It's safe to say most of us would be lost without our smartphones. Our phones help us organize our lives. They serve as an alarm clock, send us meeting reminders, take photos, play music and perform a million other useful functions. But perhaps the most important thing our phones can do for us is help us get in shape. By downloading health and fitness apps, our phones can help us run faster, work out better, eat smarter and live healthier.
