The Ab Roller is an exercise device that enhances the motion of a sit-up. Invented by personal trainer Dan Brown, the device claims to help you perform sit-ups and crunches correctly. According to an interview in Inventors' Digest, Brown's goal was to isolate the ab muscles during the exercise while reducing the strain on the neck. The device lets users perform abdominal exercises without putting their hands behind their neck. More than 10 million of the devices have been sold.
Cervical Spine Support
Thomas C. Purvis, an expert on fitness and rehabilitation, performed tests on the Ab Roller to match its claims of head support against the realities of use. Purvis found that the steel frame of the Ab Roller provides excellent cervical support. The padded headrest and design of the device allows the cervical spine to move with the frame throughout the exercise, providing support to the neck.
Intensity of the Exercise
Purvis also found that the Ab Roller increased the intensity of the exercise on the target area. By removing the hands from behind the head during the sit-up, the device eliminates any pulling that may assist in the movement. This means that the abs have to do all the work to pull the trunk up. Also, the Ab Roller makes it hard to shift during the exercise, ensuring that the movements are done efficiently and effectively.
Types of Exercise
You can perform a number of ab exercises with the assistance of the Ab Roller. In addition to stabilizing your neck during a standard crunch, the device also increases the efficiency of side crunches. You can also use it during leg lifts that target the abdominal area.
Cost
There are a few different models of the Ab Roller available. The basic Ab Roller sells for around $20, making it an inexpensive addition to any home gym. There are other packages available, ranging from $35 - $125. The mechanics of these rollers are the same, but some are made of higher grade metal, and others include instructional videos and booklets.
Ab Rollers at the Gym
If you don't have a home gym, look for an Ab Roller at your local sports club. You're likely to find one in the ab exercise area. If you need help operating the Ab Roller, be sure to ask a trainer or fitness professional.
