How OxysoxHow OxysoxTM TM worksworks
OxysoxOxysoxTMTM applies pressure to applies pressure to the lower extremities starting the lower extremities starting with the foot and narrowing with the foot and narrowing off at the calf. This graduated off at the calf. This graduated pressure allows blood to pressure allows blood to return more rapidly to the return more rapidly to the heart and lungs; the result is heart and lungs; the result is improved circulation and a improved circulation and a quicker return of oxygenated quicker return of oxygenated blood to the legs ~ enhanced blood to the legs ~ enhanced athletic performance.athletic performance.

How the How the ee33 Fitness Grips Fitness Grips WorkWork
The The ee33 Fitness Grips work on Fitness Grips work on the principle of stabilizing the the principle of stabilizing the shoulders, back, and hips. shoulders, back, and hips. During normal use the average During normal use the average person displaces the person displaces the shoulders, then the back, shoulders, then the back, which in turn shifts the hip which in turn shifts the hip position. The hips and back position. The hips and back are not always stable to start are not always stable to start with, which makes the with, which makes the shoulder girdles susceptible to shoulder girdles susceptible to the forces that would pull it into the forces that would pull it into an unstable position.an unstable position.Weight is shifted to the right;
Right shoulder is dropped and so the back arches to compensate;
The Right hip is dropped, primary muscle use in the legs is lateral;
Right knee is rotated outward
Right foot angles away from the midline of the body
How the How the ee33 Fitness Grips Fitness Grips WorkWork
The The ee33 grips help modify grips help modify mechanical behavior mechanical behavior throughout the body by placing throughout the body by placing the shoulder and hip girdles in the shoulder and hip girdles in more natural stable positions more natural stable positions and the axial skeleton in a and the axial skeleton in a balanced vertical alignment.balanced vertical alignment.
Weight stays over the midline; shoulders are Weight stays over the midline; shoulders are more stable and in a more level position; hips more stable and in a more level position; hips are level; knee tracks straight ahead (directly are level; knee tracks straight ahead (directly over the foot and under the hip), and the right over the foot and under the hip), and the right foot aligns with the mid-line of the body and in foot aligns with the mid-line of the body and in the direction of travel.the direction of travel.
How the How the ee33 Fitness Grips Fitness Grips WorkWork
The natural stable The natural stable position of the body is position of the body is possible because the possible because the grip retrains the specific grip retrains the specific contraction pattern of a contraction pattern of a person’s fingers, thumb, person’s fingers, thumb, and wrist into a neutral and wrist into a neutral position that results in position that results in better body control, better body control, improved balance, and improved balance, and better results with less better results with less effort.effort.
