Balance starts in your foot and you can’t balance without strong "balancers"!
The foot rocker is NOT just a “wobbly thing to try to balance on”! In the hands of a skilled exercise professional who understands 1) strategic progression, 2) the role of output / local tension generating capacity in the process of orchestration, and 3) COM placement, the Foot Rocker is a vital strengthening apparatus for foot and ankle muscles and therefore a PREREQUISITE for balance training.
The Foot Rocker is rigid and this is key to making it more reactive to micro-controlled positions of challenge including off-center training and end-range training.
Half foam rollers are unsuitable in this particular capacity because they smash and deform under the compression of the body weight thereby reducing both the accuracy of COM positioning and the subtle influences of the muscular forces of the various aspects of the foot. Furthermore, the radius of the foam roller is also too large to provide ideal motion.
Progress from flat side down to rocker down or vice versa depending upon the individual client and his/her needs and avail-abilities. Recommended use WITH shoes.
This third version of foot rocker offers three important new features:
1. The radius has been reduced to more closely approximate foot motion with less lateral travel on the floor.
2. The reduced radius also makes the rocker far more reactive, therefore, it is more advanced as it requires more control. HOWEVER, adding a layer of foam beneath it (~2" depending upon foam density) dampens this reactivity making it much easier and allowing for a greater spectrum of progressive challenge!
3. The edges of the top now extend beyond the radius allowing the opportunity to place "range limiters" as needed by the specific client/patient, and offering even greater opportunities for incremental progression than previous versions.
Please note that the PVC used in rocker bottom construction is heavy duty industrial grade, not "furniture" grade, and thereby is often marred (scraped or stained) during original transportation of the raw tubing. During cutting every attempt is made to insure that the marred areas coincide with the waste pieces, but there is limited ability to generate perfectly "clean" final products.
NOTE: Precise use of all RTS Exercise Tools is not as obvious as it may seem. They are not recommended for use by trainers that have not attended RTS courses that include detailed execution, progression, and cuing of/on the specific device!
In fact, if you think use of any of these tools can be generalized or standardized without considering the idiosyncratic realities of each and every individual then you obviously don’t understand it’s purpose nor the forces and internal influences associated, so please do not purchase from RTS.
