30-DAY AB CHALLENGE: ONE MONTH TO FLATTER ABS (VIDEOS)

The famous Tone House trainer Lauren Williams take you through a core-blasting series that not only nails each of your abdominal muscle groups, it works your core endurance, too.

These moves are coupled with HIIT intervals that burn fat fast—will help you check flatter abs off your To Do list no matter where you are.

The plan is that every week there is a fast ab workout that you’ll do for four days then a HIIT day, sprint day and then finally one day to rest.

After finishing every week the workout gets even harder and the time span longer for the next week.

At the end of the 30 days, you’ll be ready for the 9-minute ultimate ab assault superset.
