I think Cathe uses the medium strength Dynaband "green" For most of the new workouts. She does use a pink one in the Stretch Max dvd. The green works for this. They are 6 foot. I did use a pink one in the 4 foot length on stretch Max and it worked out ok. I did not double it in the places where she folds it. I did order new heavier strength ones for the lower body work.

Diane Sue is right, the green med 6' one came with Hardcore if you preordered. I bought some 4' ones and some other 6' ones for some variation.....Carole
