When Shaun T meant Pure Cardio, it was pure! Pure sweat and my body felt like it was gonna tear down because of the nonstop workout! I can feel my heart rate pump up and my whole body ache throughout the workout, while trying to get my breathing going! No water breaks in between the actual workout but you can rest and drink water when needed. That's what I did, then continued to finish the workout. I made a puddle of sweat on the floor doing this workout. See how insane this is? And I'm holding on week 1. My body needs to heal fast!
