Lie prone resting on your knees and elbows. In this front plank position your neck should be straight, back and abs are flexed. This is your starting position.
From the starting position, lift your hips up while squeezing your abs. You should lift them as high as you can. Hold in this position contracting your abs. Then lower down, but don’t lie on the floor. Keep your abs in the air above the floor.
In the exercise, exhale while moving up and inhale while moving down. It is important not to arch your back during the exercise.
