This workout is run just like the 12 Days of Christmas song. The number of the day of FITness coordinates with how many repetitions you do of that activity.

This is an example of how this would work:

1. 1 lap
2. 2 burpees and 1 lap
3. 3 tuck jumps 2 burpees and 1 lap....
4. etc.
(Continue this throughout the 12 days of Christmas song)

This is the list I use, however you may substitute your own list:

1. lap
2. burpee
3. tuck jumps
4. body v's
5. crossing jumping jacks
6. spider abs
7. jumping jacks
8. switch split lunge (plyo lunges)
9. box jumps
10. jump ropes
11. sit ups / crunches
12. medicine ball twists

This can be modified in any way to fit your class fitness level.

I also use the same concept in the weight room for a 12 Days of LIFTmas.
