need help selecting a DVD to use at home. I have been going to a health clubs intermediate / advanced step class for 15 - 20 years and am now moving to an area that is too far from a club. The music is important to energize me and have recently started enjoying the hip hop type in class. I like a quick beat and sometimes a lot of base. I will be working out on a berber carpet that has a thick pad underneath, does anyone have a comment on this type of surface for a step routine? I have looked at the web site but just get confused can you suggest which items would be best for me?
