Spin Strong is the air resistance based rotary trainer that includes a pair of handheld units; each comprised of a sturdy handle with a set of premium ball bearings, a 17 inch durable spin cable, and five plastic multi-fin air resisters. Each unit weighs only 5 ounces.
An instructional exercise poster is included that covers using Spin Strong for jump rope exercise, full body training and strength training, including diagrams for the nine key Spin Strong exercises.
The spin cable is designed to hold an additional air resister, a pair of which can be purchased separately.
