The isometronic training method is a powerful way to build muscle size and strength. Think of it as rack training—on steroids!

Traditionally, it requires two sets of safety pins on each side of a power rack, allowing you to target the top, middle, and bottom third of a lift’s range. After completing a number of reps within the designated range, you typically perform an overcoming isometric by pressing against the top pins before resting the bar on the bottom pins.

But what if your power rack only has one set of safety pins?

No problem. Instead of doing an overcoming isometric against the top pin, try a yielding isometric just shy of the bottom pin. This variation still produces excellent results—and this video will show you exactly how to do it:
