An ab crunch bench is one of the most popular fitness choices for in-home exercise, as this seemingly simple piece of equipment allows for seriously targeted ab workouts. Just a few minutes a day on a Pure Fitness Ab Crunch and Sit-Up Bench can give you a stronger core, flatter stomach, slimmer waistline and six-pack abs much faster than almost any other exercise routine. The sleek design of this bench is not only space efficient, but built on a sturdy 50mm square and tubular steel frame that can handle your most vigorous workouts without slipping or shifting. Well-padded knee and ankle rollers allow you to comfortably lock in your legs for a true isolated ab crunch workout. The ankle roller adjusts to four positions, ranging from 10 inches to 16 inches apart for the proper fit to accommodate a range of heights. The soft, 2-inch, high-density foam pad upholstered with heavy duty water-resistant vinyl makes even extended exercise more comfortable, and it wipes down easily. When you're finished, the bench folds down for easy storage.
