This may only be of interest to a small subset of you gadgetites out there, but I found it interesting nonetheless. The Manta Ray from Advanced Fitness, Inc. is a patented device that can help alleviate neck pain when performing a squat exercise. Made of molded polyurethane, it features a notch that grips the squat bar while the contoured shape distributes the weight of the bar across a greater surface area of the neck, upper back and shoulders to relieve some of the concentrated stress in that area. Available in one size for $39.95. Also available in a front squat version called the Sting Ray for the same price.
