The Ab Hero Next Level challenge is all about pushing you to the next level. This is our advanced level of our Ab Hero fitness course which is aimed at strengthening your core strength. We recommend doing this only after you have completed the 21 day Ab Hero Challenge and feel strong and confident in your ability. Just because you have completed the intermediate Ab Hero challenge doesn't mean you are ready for the advanced course. Remember we are focussing on long term fitness here so do this when you feel ready.
