Welcome to the new 2-Week FB Abs Challenge!

This 2-week challenge comes with FB Plus at no extra charge, but if you are not an FB Plus member you can still get in on the fun with a Plus Pass. It is also important to note that the FB Plus version of this program comes with extra content and options scattered throughout the two weeks. See all FB Challenges here.

You'll be doing a different workout video every single day, resulting in a highly dynamic workout challenge that not only targets your core, but is also great for burning fat, building muscle, and helping you to move and feel like an athlete. This program aims to build a stronger core which will benefit you, your fitness goals, & your quality of life in ways far beyond the superficial goal of a flatter or more toned stomach.

This is NOT your typical abs program and this plan is not just a bunch of repetitions of core exercises. The combination of core, HIIT cardio, and strength training is effective for allover toning, reducing body fat, improving cardiovascular endurance, increasing lean muscle mass, functional strength, agility, coordination, flexibility, and balance. With these workouts and a healthy diet, you can definitely see improvements in mobility and ability, as well as drops in body fat and scale weight. If you like this two week version, then you may also interested in our previous 4 week versions FB Abs Round 1 and FB Abs Round 2.  

Workouts are scheduled five days a week (three weekly core intensive workouts, every other day), range between 30-43 minutes, averaging out to 36 minutes a day. Dumbbells are used throughout the program & are recommended but not absolutely necessary. Three times a week, we provide an optional "Extra Credit Challenge" workout, in case you have the extra time and energy. 

We encourage you to visit the Fitness Blender Community Forums to find support from the most encouraging fitness community on the web. You can also use #FBabs on social media to track your workout sessions, share your progress, find motivation, and connect with people around the world who are following this program or challenge. 

Difficulty level: Though we always encourage each person to listen to their own body's messages and move at their own pace through the workouts, the routines in this plan are relatively intense and start out at difficulty levels 3-5 from day 1. This is not a low impact program, though many of the workouts (not all) provide low impact options. Exercisers will need to use their own discretion in manipulating the scheduled workouts to be appropriate for their personal fitness levels & abilities. Exercisers are encouraged to take liberties in manipulating this program to work for their needs.
