Remember this workout? Five months ago in Hawaii, I cobbled it together from various P90X sessions, and it kicked my butt -- despite the fact that it didn't take long to complete. Given that I only had an hour to kill between meetings, I decided to give it another go today.
This workout is perfect for when you're short on time and stuck in a hotel fitness center with a rack of dumbbells and nothing else (other than a bunch of weight machines and treadmills). I did each set to exhaustion, and rested for 30-60 seconds in between. The entire workout took only 35 minutes, but I'm beat.
