And now they’ll show you how to ‘snack’ properly

Although there’s no fitness snack that’s too small — any exercise is better than nothing — the evidence is a bit stronger to support 10-minute chunks of moderate aerobic activity, fitness expert Cedric X. Bryant says, a position that the American College of Sports Medicine also supports.

He recommends finding 10 minutes each day for a mini-workout that combines cardio intervals with body weight strength moves.

“The key is to keep moving the whole time,” Bryant says. And to combat excuses, he recommends getting creative with where you squeeze your fitness in, such as push-ups during television commercial breaks, or walking lunges when you watch TV.

Snack-sized bites of fitness like these can make exercise seem less daunting, but to make it effective, find the pace, intensity and activity that works for you, says trainer Gunnar Peterson, who works with celebrities, as well as the Los Angeles Lakers.

“More than anything, try to have fun with it,” Peterson says. “Because if it’s not fun, at the end of the day as proud Americans we’ll say, ‘I don’t have to do this.’ If it’s fun, it promotes the return.”
