Run 1 mile = subbed in bike 2 miles actually went 2.15

Mix and match back extensions and sit-ups as needed.

Biked 2.15 miles each round for the mile. Bike is about to blow up on me so I had no breaks and had to be careful on the turns when I normaly would have cranked the whole time and breaked at the turn. Oh well. Back extensions killed my hamstrings. Tweeked my back between my shoulder blades today at track practice (Levi). In some pain. I also ran a bit doing hand offs. It felt good at the time but I am paying for it now. My dang legs are numb. I know I have done this workout before but I can't find it.
