Blogilates treadmill workout... Maybe start with half of this at first and work up to the whole thing?  Have a funny feeling this would currently kill me.

I hate the treadmill but for those who don't: TREADMILL SHREDMILL WORKOUT! It's 45 min long with a 5 min cooldown. This is part of my bikini comp cardio. And yes, you CAN last this long on a treadmill. Trust me.
