How varied are your workouts? Varying the way you train and adding new challenges to your fitness program helps you continue to make gains and avoid those frustrating training plateaus. Variety also adds an element of novelty and fun.

One form of training you might not be familiar is called PHA or peripheral heart action training. This type of workout structure closely resembles circuit training but with a twist – it stimulates your muscles and cardiovascular system in a slightly different manner. PHA training was developed by Dr. Arthur Steinhaus popularized in the 1960s by Mr. Universe, Bob Gajda and is still an effective way to get a workout today.
