No one yet has said PS Legs and Abs. It's my favorite because the pace is slow enough,there are breaks, and the floor section just does what nothing else can do for me.
I, like Janice, also enjoy higher weight with lower, slower reps. Endurance weight work is something I have not yet mastered. Power hour is amazing with Cathe using 35 pounds. It will be a long time, if ever, before I can do that.
I also like S&H but my all-time fave is Pure Strength Legs and abs. It's available all by itself you know (VHS). The DVD has the whole series. The whole series is great, IMO.
