Motion training aid with stimulator

A biofeedback stimulator comprising:

• a first skin electrode for making electrical contact to a body of a user;
• a second skin electrode for making electrical contact to the body of the user;
• a body capacitance charging module connected to the first skin electrode;
• a discharge module connected to the second skin electrode for a feedback discharging of a body capacitance charged by the body capacitance charging module;
• and
• a processor connected to the body capacitance charging module for controlling the charging of the body capacitance to a predetermined first voltage level,
• wherein the processor further being connected to the discharge module for controlling a feedback discharge of the body capacitance through the skin via the first skin electrode and the second skin electrode,
• wherein the biofeedback stimulator further comprises a measurement module for measuring a level of charge of the body capacitance, and
• wherein the processor is configured for keeping the biofeedback stimulator ready to discharge by repeatedly measuring the level of charge of the body capacitance and by providing a maintenance charging by activating the body capacitance charging module when voltage of the body capacitance is at or below a predetermined second voltage level.
