What is the Fibonacci sequence?

A sequence where each number is the sum of the two preceding ones: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55... Named after Italian mathematician Leonardo Fibonacci.

Where do most people finish?

Most athletes complete through the round of 13 (total: 1+1+2+3+5+8+13 = 33 of each) and get into the 21s. Elite athletes complete the 34s.

How should I break the cleans?

Go unbroken through 8s. At 13, consider 7-6 or 4-3-3-3. At 21, break into sets of 5-7. At 34, break into many small sets.

What's the total if I finish the 34s?

If you complete through 34-34: 89 double-unders and 89 power cleans. The 55s add another 55 each.
