Maximum Intensity Challenge!

Maximum Intensity Challenge is a 60 min advanced cardio workout lead by Cathe Friedrich.  After a nice low impact warm-up Cathe leads you through a good low impact section then to a good medium impact section to a hard very hi impact section on the floor.  The last section is a nice cardio step section that was fun to learn.  This is one tough workout and the next time I do it I will skip the high impact section and just do the other sections.  I do not like Cathe's Hi/Lo workouts as they tend to be mostly long Hi/Hi sections with no low impact at all in them.  I give this workout 3 1/2 out of 5 stars.
