Hyperwear SandBell Neoprene Sandbag Free Weight (Unfilled)
The Hyperwear SandBell re-invents free weight fitness equipment. Use the Hyperwear SandBell as you would a medicine ball, slam ball, dumbbell or kettle bell. Prepare to work muscles you didn’t even know existed. The active, shifting movement of the sand challenges stabilizing muscles in your core and burns more calories than static weights. When working out with the Hyperwear SandBell, you will engage hand- and wrist-gripping muscles that are typically not activated and strengthened. Because the dynamic shifting sand weight can burn more calories with the same workout, Hyperwear SandBells have been featured as the perfect part of a weight loss fitness program by the Dr. Oz Show, Prevention Magazine, Shape.com and Weight Watchers Magazine. Another advantage of this product lies in its safety for you and your floors. On a slick floor you can use Hyperwear SandBells for a variety of sliding core exercises to build better abs. Its outer cover, made of durable, stretchy neoprene, contains a leak-proof core that can be easily emptied and filled with dry play sand. Dry washed play sand is recommended for use with Hyperwear SandBells, which can be obtained at most major home improvement stores. Employ a funnel for easy filling. Empty SandBell weight is approximate, as you can determine your own amount of fill to make the Hyperwear SandBell more solid or squishy as you see fit.
