This is an advanced plank exercise that will have you turning on and firing up your muscles. Note of caution always listen to your body. If you feel straining or pain in any area of the body stop the exercise immediately.

A progression of plank.

Slide your body back and forward while keeping the core braced.

I would consider this an advanced core exercise.

If at anytime you feel your back you’ve lost engagement of the core.

Stop the exercise.

Listen to your body.
