Walk benefits...

This one may seem obvious, but it's certainly a happy benefit for those who start walking regularly. "As you continue to walk, you may notice your pants begin to fit more loosely around your midsection, even if the number on the scale isn't moving much," she says. "That's because regular walking can help improve your body's response to insulin, which can help reduce belly fat." Ariel Iasevoli, a personal trainer at Crunch gyms in New York City, adds that walking every day is one of the most effective low-impact ways to mobilize fat and positively alter body composition. "Daily walking increases metabolism by burning extra calories and by preventing muscle loss, which is particularly important as we get older," says Iasevoli. The best part? You don't have to slog it out on a treadmill at the gym to see these benefits.
