While spinning, attempt to pull up on the crank bearing.

One of Lance Armstrong's coaches described it as spinning as though riding over red hot pavement and trying to pull one's feet up.

One still spins a full 360 degree circle, but adusts the forces as if to keep an upward pressure on the crank bearing.

If one wants to spin faster, he should pull up on the crank.

If he or she wants to spin slower, he should put more weight on the crank.
