2. The exercise load can be adjusted in the following way: Add if there is only soreness, reduce if there is pain and stop if there is numbness. When there is muscle soreness with a feeling of heaviness and distension while raising the arms (this is a normal reaction to the exercise), the exercise load should be increased. Increasing local pain indicates an incipient inflammation of muscles or tendons, and the exercise load should be reduced to avoid extension of the inflammation. Numbness is a sign of pressure on a local nerve, suggesting incorrect practice. Stop the exercise at once to find out the cause and resume practicing only when the faults have been corrected.

3. Be sure to take off the overcoat before exercising. In the winter, you may leave the overcoat on until after one or two steps and put it back on immediately after exercising to avoid catching cold. Change the undershirt if it has been dampened by sweat.

Contraindications:1. Suspend exercising if there is acute local inflammation, high fever or hemorrhagic symptoms.
2. No practice should be performed during emotional upset, for on such occasions the requirements of movements can hardly be achieved, and excessive actions may cause injury.
This kind of patting is especially suitable for the aged with weak constitutions and soreness in the back, shoulders and arms. Though simple, it offers good results if it is performed consistently.
