Hi guys,
In regards to Cardio Pump - It is a shorter workout, about 50 some minutes, and it starts out with a short, hi impact, intense hi/lo segment, then it is followed by a weight segment using dumbbells, tubing, etc. It is not my favorite Amy workout, but there are premixes to make the workout longer ( ie double cardio, etc..)
Of this series I probably like her Bootcamp dvd the best.
HLX and KBX are about 70 minutes from start to finish,( don't quote me on the exact times ), the cardio portions being 60 minutes in themselves. Great premixes are here also to lengthen or shorten your workout.
Be aware that Amy does little or no breakdown, and HLX is higher impact. Some people have issues with her kickboxing ( believe me, these posts pop up under just about EVERY Amy thread, just in case you forget for a few minutes..;-) ).
I like her and find her refreshing and spirited, and I see a very bright future for her in the DVD industry.
Enjoy!!!
