Pete Sisco is the author/editor of more than a dozen books on strength training. He is the foremost expert on Power Factor and Static Contraction training.

His books have been translated into Japanese, Italian, Swedish and Russian and his e-products have sold in over 100 countries worldwide.

Since 1992 all of his muscle building methods involve using objective measurements of the intensity of each exercise and closely tracking performance to reveal progress, plateaus, and regression during training.

Now retired and living in Thailand, Pete revised and updated his famous POWER FACTOR WORKOUT in February, 2026.
