Overview

The PowerBlock crunch is a great exercise for developing your abs and strengthening your core. This exercise is exactly the same as a regular crunch done while hugging a PowerBlock dumbbell to your chest. To progress with this exercise you can add repetitions or you can add more weight.

Description

• Lie on your back with your legs bent and feet flat on the floor.
• Hold the PowerBlock dumbbell at your chest, close to the chin.
• Keeping your neck neutral, roll your upper back off the floor.
• Return slowly to the floor.

Mistakes

• Jutting the chin as you crunch.
• Holding the PowerBLock dumbbell too low toward the stomach
