This was WAY harder than it seems from the title screen. Circuit 2, I was thinking oh this is easy. Circuit 4 and 6, OMG. My arms were dying. By the end, I had sweat dripping down my face and this was not a cardio workout!!! I did like the cardio mixed in- I do feel like I need atleast a bit in every workout and oddly enough, I am a big fan of burpees! So YAY- this was a win for sure.
