Hardcore Extreme is a compilation of IMAX 3, Kick Max, High Step Challenge and Low Max. H.C.E. #1 is an interval circuit workout (71 mins.) with IMAX 3 and High Step Challenge. H.C.E. #2 is a hi/lo workout (73 mins.) with Low Max, IMAX 3, Kick Max Blast Challenge and Kick Max Stretch. H.C.E. #3 is interval blast plus legs (69 mins.) with IMAX 3, Kick Max Blast Challenge, Kick Max Leg Conditioning Drills and Kick Max stretch. They are all great, killer workouts. IMO it is definitely worth getting.
