Have You've Ever Wondered Where PHA Training Originated?


Staff member

STEP BOSS PHA 3 is our third video using the PHA training method, but have you've ever wondered where PHA training originated? PHA training dates back to the 1960s when Mr. Universe, Bob Gajda, popularized it.

To this day, serious bodybuilders use it when they want to shake up their routine. Like circuit training, it’s a dynamic and fast-paced way to work out and one that places greater demands on your cardiovascular system, yet still leads to gains in strength and muscle size.

The way you structure PHA training is to alternate an upper body strength training exercise with a lower-body one. As with circuit training, the goal is to keep the rest periods between each exercise short. By alternating between the upper and lower body with minimal rest, you keep the demands on your heart high.
