If you are ready to take your ab workouts to the next level, this exercise is for you! The plate crunch can be used as a progression to the traditional workout ball crunch. The range of motion is virtually the same. However, a bar plate is placed behind the head to increase difficulty.

Grab a bar plate and place it behind your head. Position the workout ball on the middle of your back. Ensure you are flat on the ball. The plate should rest comfortably behind your head. Next, slowly crunch the abs and exhale. Your upper torso should only come up a few inches. Hold the position for 2 to 3 seconds and repeat the exercise.
