GET A FLAT STOMACH IN 5 MINUTES: WEEK 2 PROGRAM (VIDEO)

In this plan, you’ll perform one five-minute workout five days a week for four weeks, taking two rest days per week whenever you want them. At the end of each week, you’ll progress to a more difficult workout.

Each workout is made up of five exercises designed by New York City-based fitness trainer Chelsea Dornan. For each move, do as many reps as you can in 60 seconds. Then move on to the next exercise. That’s it!

THE MOVES
