Our Better-Butt Challenge has 21 days of workouts to help you take your butt from flat to full. In the end, you'll have a tighter, stronger backside. Today is all about cardio! Be sure to check back tomorrow when we share the next workout of this three-week plan.
It's time to hop on the treadmill; not only will today's workouts help build a strong, shapely backside, but a dose of cardio will burn calories and melt away fat to help show off all that tone. Today, choose from two workouts depending on your running skill — a hilly treadmill run or a slower walk on higher inclines.
This rolling hills workout works your backside while burning major calories, too.
Not a runner? Try this walking treadmill workout that will ensure you feel the burn.
