Who should use the Proprioceptor Plugs? Anyone. Some would think only athletes in sports such as basketball, football, soccer, or tennis would need these, but there are virtually no limits! Skiing, snowboarding, figure skating, gymnastics, martial arts, and ballet are just a few of the other activities that can be greatly enhanced by the Proprioceptor system. But this is only looking at the athletic benefits. Balance is an essential element in everyone's daily life! The Proprioceptor system is great for rehabilitation for injuries and simply strengthening ankle joints. What is the Proprioceptor? Proprioception is a form of training that is the most exciting recent development (and also the least known to the public). Proprioception uses controlled destabilization to multiply workload and sharpen neuromuscular reflexes. Team trainers have discovered that their athletes are more sure footed and injury free, with faster results than traditional workouts on a flat surface. The new Jumpsoles v4.0 are the only platform trainers on the market that have proprioception capability. The controlled imbalance created by the Proprioceptor Plugs forces your brain to fire impulses to your muscle fibers over one thousand times per second. The loading stimulus is radically supercharged, like nothing you've ever felt before. After just one workout you'll feel the amazing difference in your game. You'll blow past defenders with your first step quickness. Available in sizes S-XL.
