## The Thirteen Minute Drill

**Training with “Fibonacci’s Rabbits”**

Be sure to Set the Clock and Time the total workout

Be sure to go from one exercise to the other in each “superset” group. Finish all three sets of eight before moving on to the next group of supersets.

**Set the Equipment and Warm Up**

Group One

Snatch from the Hang or Romanian Deadlift: set of Eight

Front Squat…with Chains: set of Eight

Repeat both exercises for Three Sets of Eight.

Group Two

Military Press: set of Eight

Deadlift or Variation of Deadlift: set of Eight

Repeat both exercises for Three Sets of Eight.

Group Three

Sidebend to Right: set of Eight

Sidebend to Left: set of Eight

Repeat both exercises for Three Sets of Eight.

Group Four

One Arm Press, standing, with Right: set of Eight

One Arm Press, standing, with Left: set of Eight

Repeat both exercises for Three Sets of Eight.

Group Five

Curls, any variation: set of Eight

Tricep Work, any variation: set of Eight

Repeat both exercises for Three Sets of Eight.

Quickly record total time (all five groups) after last set of last exercise. Try to beat it next time. When you get to 13 minutes for the whole workout, add weight to each exercise next time.

*The original problem that Fibonacci investigated (in the year 1202) was about how fast rabbits could breed in ideal circumstances.

Suppose a newly-born pair of rabbits, one male, one female, are put in a field. Rabbits are able to mate at the age of one month so that at the end of its second month a female can produce another pair of rabbits. Suppose that our rabbits never die and that the female always produces one new pair (one male, one female) every month from the second month on. The puzzle that Fibonacci posed was…

How many pairs will there be in one year?

At the end of the first month, they mate, but there is still one only 1 pair.

At the end of the second month the female produces a new pair, so now there are 2 pairs of rabbits in the field.

At the end of the third month, the original female produces a second pair, making 3 pairs in all in the field.

At the end of the fourth month, the original female has produced yet another new pair, the female born two months ago produces her first pair also, making 5 pairs.

So, these numbers are: 1, 2, 3, 5, 8, 13, 21, 34, 55…
