Product Story

This is the handheld kinetic resistance trainer that gives time-starved fitness seekers a total core workout in just four minutes at home or the office. The culmination of 16 years of research and 36 global patents, this core trainer delivers the benefits of four full-size core machines by simultaneously activating 46 core muscles and eight arm muscles. As users draw their torso in from a seated, standing, or supine position, the trainer’s upper and lower power modules independently provide variable resistance. The result is an intense core and arm-strengthening workout you can perform in just four minutes, unlike the complicated, cumbersome devices or free weights that require a dozen different exercises and 30-50 minutes. Constructed from lightweight, durable molded resins, the trainer adjusts easily for most users and folds down for convenient portability and storage. A smartphone dock lets you run a free exercise app to monitor your workout. Includes one upper cartridge (up to 60 lbs. resistance) and one lower cartridge (up to 70 lbs. resistance). Interchangeable cartridges with lower or higher resistance modules are available from the manufacturer. 9" H x 18 1/4" W x 23 1/4" L. (7 1/2 lbs.)
