TopSpin 360 is a patented neck strengthening tool that utilizes a multi-planar force to produce a neuromuscular response.  The TopSpin 360 allows for multiple neck contractions occurring quickly when the user spins the topspin device at a high velocity. 

 

The TopSpin 360 elicits the stretch reflex of the neck musculature producing plyometric like effects.  In other words, the device promotes similar physiological adaptations as plyometric training, thereby improving hypertrophy and increased strength. 

 

The high-speed eccentric contractions experienced are similar to that of parachute landing and should be considered the optimal form of training for the military paratrooper.  Please watch the videos provided in the link for sets and repetition, and Topspin 360 information.
