5 minute bike warmup.

3 x the following:

40 sit-ups
20 reverse sit-ups
40 russian twists
20 supermans

12 deadlifts (20 lbs)
15 reach up lunges
15 reach down lunges
15 lunges with 30 lbs.

The last time through doing the 40 situps? Not pretty. Legs were really
shaky afterward. Stretched really good, though. Surprisingly.
