Just got in some @PowerBalance bands. These things are Amazing!
They functionality is described as such:
Worn by pro athletes like Lamar Odom, Shaq, Shane Del Rosario, Ricky Romero and Matthew Stafford, Power Balance will increase your athletic performance. How does it work? Nearly everything has an inherent energy frequency.
Some frequencies react positively with your body and other react negatively. When the special hologram in the Power Balance bracelet comes in contact with your body’s energy field, it allows your body to interact with the natural, beneficial frequency stored in the hologram. The results are improved energy flow throughout your body. Crafted from 100% neoprene with a comfortable spandex lining, the bracelet comes with two holograms to take your athletic performance to a whole new level.
Other potential results include flexibility, strength, balance, better recovery, ion balance restoration and improved concentration and focus. Wear the Power Balance Neoprene Bracelet just for your sport or all the time.
One of the many products they have is the Silicone Wristband.
