The 21 Day Shred is our most popular training series—two years in a row. If you’re not quite ready for the full plan of circuits, bodybuilding splits, intervals, and cardio challenges—why not give the ab workout a run-through? Like what you’re hearing so far? It gets even better… The 21-Day Shred has recently expanded into a four-part series called The Shred Series. Program followers now have the option of completing the original shred, along with three more 21-day body-transforming programs.
But whether you’re SHREDDING, or not, here’s the ab workout can you add to your current arsenal.
