This 21-Day Abs Challenge will strengthen your entire core. Thanks to a combo of strengthening exercises using bodyweight, dumbbells to a BOSU (optional) this 21-day Abs Challenge will help you build your most powerful core yet.

Now, remember we can't spot reduce body fat (ie. this challenge will not burn your belly fat), instead what this challenge will do is give you doable ab exercises, in 10-minutes or less, so you can strengthen your abs and deep core muscles. We have kept the workout time short, so this challenge does not interfere with your regular fitness.
