Cardio Supersets
Athletic Training
Afterburn
Turbobarre
I can't decide on 3 so I have to say 4 and these are not in any particular order. I reach for Turbo barre more than any of them and I am not into barre workouts. For me - it's just that good.
I didn't say Total Body Tri-sets or the yoga - cos although they are good - I have others just as good in my collection. Cathe has a lot of great weight training workouts.
