Ab Rollers: 5 Fast Facts

Fact #1. The first patent for an ab roller was approved in 1968. It was filed by an American inventor. He described his wheel as an exerciser with grippers on a roller mounting shaft. It was almost identical to the models that we use today, a pair of parallel wheels connected via a metal bar which was housed in rubber grips on either side.
Fact #2. The initial ab roller was effective. Its primary drawback was that it didn't allow for adjustments to the wheel's resistance. Another inventor tried to capitalize on this by developing a model during the early 1970s that was comprised of a pair of spherically-shaped metal weights. They ran parallel to each other while being encased beneath two orbs. This device succeeded in providing more resistance. However, it failed in that the resistance wasn't adjustable.
Fact #3. A pro wrestling hall-of-famer became an early champion of the device. Physical trainers were making consistent use of rollers, as well. They came into their own as a result of daily infomercials throughout the mid-to-late 1980s. Manufacturers had determined how to allow for adjustments to the wheel's resistance. These running infomercials rendered the ab wheel a constant presence on late-night TV.
Fact #4. Pushing an ab roller is a little like riding a unicycle. The wheel and the axle both need to be durable, and capable of responding to an overwhelming shift in weight. The wider the wheels, the more stable that roller should feel whenever it is rotating, back and forth.
Fact #5. Top-of-the-line units can be adjusted for resistance. As your abs strengthen, you can continue to build muscle by pushing harder, as opposed to doing more, or moving slower. The majority of top options also feature foam hand grips, which are removable, machine-washable, ideal for absorbing sweat, and custom-made for avoiding blisters between the fingers and the thumb.
