Friday's Workout-20 minutes of stairs

This was a rough workout, I did them in the stairwell of my high school. The stairwell has 4 flights of stairs  & 24 steps per flight = 96 stairs. I ran all 96 steps 18 times. In between each set of stairs I did a specific core exercise, which I will post at the end of this entry. For the first 14 sets of stairs, I stopped my watch whenever I did abs. However, it started to get late and I felt like I needed to get home, so for the last 4 sets I had to let it run so I could finish the workout. The entire workout is as follows:

stairs-every step
25 pushups
Stairs-every step
50 crunches (straight)
Stairs-every other step
25 squats
stairss-every other step
30 seconds of flutter kicks
stairs-every 2 steps
25 push ups
stairs-every step
50 crunches (side)
Stairs-every step
50 crunches (side)
stairs-every other step
25 squats
stairs-every step

I did this routine through twice in 21 minutes.
