Just to let you all know - I own pretty much all the Cathe workouts minus the Hardcore series and Pure Strength series.......I even preordered her new ones........
I LOVE to lift but need to get more cardio I enjoy as well. In the winter I am stuck inside due to snow.....
the two GS upper bodies! (i use those most along with kickmax and GS legs that you have) sooooo i get to pick two more....
the next ones i use most are: muscle max and (uh oh....) kinda tied between high step challenge and low max (low max seems to be reeeeeeeealy popular... i like it.. but not as enamoured as a lot of others... i think i would pick high step challenge over low max.. but that's just me!)

cute work out clothes are good for AT LEAST an additional 10-15 calories burned!
