The idea with the Racket Bracket and Memory Board is that they help groove in "muscle memory". By consious repetition with a device that guides you in the correct execution of the stroke, the player actually trains the brain to perform that movement naturally. When the same movement is performed without the device the brain "remembers" the repeated stroke and performs is "naturally".
This is such an important concept in the learning process in just about everything, and the critical idea is that when we learn something, it tends to "stick" whether it is "correct" or "incorrect", "right" or "wrong", optimal or detrimental. In Modern Tennis Methodology we spend a lot of time with players trained conventionally to "unlearn" those strokes, body movements and ideas that are actually preventing them from performing optimally. Beginners and little kids do very well with MTM because they have not learned patterns of movement or mental concepts which complicate and distract the player from playing his best. The basics developed by Oscar promote a simple, clean execution of technique and approach to tennis, and are applicable to players of all ages and levels from beginner to Pro. This is difficult for some to understand until they have experienced it, but it does work in practice.
Our goal on the MTM forum is to educate players about another, simpler way of approaching the game in order to help them play their best and maximize their enjoyment of this wonderful sport. It is each individual's choice whether to take advantage of this data, and I applaud those who are open-minded (or desperate LOL) enough to give it a try. We let the results speak for themselves.
Looking forward to hearing Chips' results with the two devices - they may not be for every player, but Oscar has seen good results with them for many.
