Frank Shamrock ranked No. 1 during his peak in the UFC Middleweight Champion.

As he shares his love for the sport with others he’s developed a system to produce the best outcome.

He calls it the plus, minus, and equal approach.

“Each fighter, to become great, he said, needs to have someone better that they can learn from, someone lesser who they can teach, and someone equal that they can challenge themselves against.”

The same can be said about any occupation.
