As I was working out, I realized something. Jillian says throughout the video that we have to make our bodies adapt and do what we want them to do. We can't quit when we get tired or our bodies won't learn to change.
It's so true! As I actually made it through the ridiculous workout - as Jillian was telling me she wanted me gargling my heart by the end of it - I realized that my body was adapting!
I still hate it - especially squat thrusts - but at least I can tell that I'm forcing my body to adapt.
