An ab roller is a piece of fitness equipment with two handles and a wheel in the middle. It is used to perform exercises that target the abdominal muscles, including the rectus abdominis, transverse abdominis, and obliques. Ab roller exercises are effective for building core strength, improving posture, and reducing back pain.
There are many different ways to use an ab roller, but the most basic exercise is the rollout. To perform a rollout, kneel on the floor with your knees hip-width apart and your hands on the handles of the ab roller. Roll the ab roller forward until your body is fully extended, then roll back to the starting position. Repeat for 10-12 repetitions.
