Hello!

So I've been doing the 30 day shred, but I was wondering exactly why it works/what the science was behind it (besides Jillian's explanation in the L1 video).

Thanks everyone! Hope you are having super duper days!

    circuit training works because the bursts of cardio in your strength workout keeps your heart rate pumping (read burning calories) while you strength train different muscle groups - - Kinda falls into the don't work harder, work smarter category.

    well im nnot sure about the science behind it but I did it and lost alot of inches.....I think its the major up and down intervals that burns so much calories and the isolation exercises with it....thats just my 2 cents :)
