Instability is the new “black” in the fitness world. We’ve seen it permeate every type of workout equipment, and now we’re adding dumbbells to the list. Why? Because we’ve had a chance to use SandBells. The SandBell ($8-$85) is a cross between a sandbag, a dumbbell, a barbell, a grip bag, a medicine ball, a slam ball, a stability pod, a gliding disk, and a kettlebell. Seriously.
We like them because you can mix up a stagnant routine and engage under-utilized muscles groups in the process. If you can’t find a weight that suits your needs, you simply adjust the sand (or other fill) volume to your desired. Each SandBell is constructed of thick neoprene so it’s both soft and stretchy (adding to the instability), but durable enough for a daily abusing. They’re even small enough to keep one at your desk, but challenging enough to use at home when you can’t make it to the gym.
