The Spin Strong Rotary Trainer is the first compact, air resistance based jump rope exerciser and strength trainer.
It includes a pair of lightweight trainers with premium ball bearing handles, 17 inch durable spin cables and six symmetrical, flexible plastic air resisters per side. Each air resister is comprised of three fins extending out from a longitudinal hub. The configuration of resisters is easily changed from six to five or less. Each trainer weighs less than 7 ounces.
An instructional exercise poster is included and covers jump rope exercise, changing the configuration of air resisters and strength training, including diagrams for the nine key exercises.
