Crunches are bad … here’s why

December 25, 2018

I spend most of my day hunched over a computer. That’s bad. It’s causing my spine to curve like a C, which is the wrong way for the spine to be curved.

The spine should be curved the other direction.

Crunches are bad because with every rep the abs are pounding on the spine to flatten out. But the spine should not be flat. The spine should be arched.

No more crunches for me.

In fact, no more exercises that pound the spine into flatness, which means no more upside-down leg press, no more flyes with legs up on the bench, etc. And certainly, no exercise that curl forward.

Stop stretching

January 14, 2018

I hear this advice all the time: Do stretching. Get flexible.

That is bad advice.

Your muscles are like springs. Kind of like the springs in your car. Do you want loose springs in your car? Of course not. You want firm springs.

When you bend down to pick up an object, you want tight hamstrings (ham-springs) to firmly move you back up to the standing position.

The back is not designed to bend or twist. It is designed to stop motion and hold your torso stiff. Stop doing crunches, sit-ups, bends, and twists. They will ultimately harm your back.
