The purpose of this program is to strengthen the core. We are not aiming to build a visible 6 pack, though that may be a an additional byproduct depending on your body fat percentage. Exercises are to be done in a circuit and this program can be tailored to any level of fitness. For those newer to exercise, especially core work, or those who have a weak core, it is recommended that you start with just the first exercise. Once you can hold all 3 of the first exercises on the list for 60 seconds you can begin to add the rest. Start at a level comfortable for you, but push out of that comfort zone as you progress. This program can be added to supplement any program you are currently doing, especially if that program has no direct core training included in it.
