One of the funny things about flat abs is that to get them, you don't necessarily have to do workouts that directly involve your stomach. Rather, it's just as effective -- if not more so -- to focus on exercises that engage your core as well as other parts of your body, like your thighs, glutes, and arms. Enter: This five-minute workout video.

All you need is two sets of dumbbells -- one heavy pair and one lighter pair -- and a mat. There are five moves total, and it's your job to do as many reps of each move as you can for 50 seconds, with a 10-second break in between each one. If you have more than five minutes, you can start the video over and do it two or three more times -- but doing it once is totally fine, too!
