These innovative fitness free weights by 7 nepo take inspiration from an unlikely, surprising origin — Matryoshka Russian nesting dolls! Like the doll-in-doll system, additional weight may be inserted by massaging the weights together. With a quick snap-in/snap-out mechanism, you can transition from light to heavy in seconds to accommodate your workout routine without interruption. When you’re finished lifting and want to squeeze in some aerobic, the handles twice as a jump rope by connecting an included cord. Even better, they make a cute desktop trinket if you are not using them!
