Device for performing physical exercises, in particular for motor rehabilitation exercises

A kit comprising:

• a device for physical exercise comprising:
• a body with a casing that defines an inner chamber designed to be filled with a pressurized gas, said casing comprising at least a part that is a translucent or transparent material and at least a part that is a flexible material, said body having at least an opening, communicating with the inner chamber,
• a closing element housed in the opening and configured to couple with the opening of the casing, said closing element comprising a head portion and a support portion extending from the head portion towards the inner chamber, and
• a plurality of components mounted on the support portion, the components comprising
• at least one pressure sensor positioned to detect a value of a pressure in the inner chamber,
• at least one light source,
• a first controller connected to the at least one light source and the at least one pressure sensor, the first controller being programmable, the first controller being configured to receive a measurement of said pressure value and to control an activation state of the at least one light source according to said pressure value, the first controller being configured to store and set a threshold pressure value, the first controller comprising an initial calibration function to record said threshold pressure value prior to a beginning of exercise, said threshold pressure value corresponding to a greatest compression force exerted by a user or a specific level of compression force exerted by the user, the first controller being configured to control, during use of the device, activation of the at least one light source in order to signal, with one of a specific color, a specific sequence of blinks, and a specific light intensity, an entity of the pressure value detected according to the stored threshold pressure value,
• a first communication system connected to the first controller,
• a battery that powers the components, and
• a recharge circuit for the battery that includes at least a coil or loop of conductive material located in the head portion of the closing element or electric contacts protruding from an outer surface of said head portion;
• and
• a support for the device, the support comprising
• a second controller, and
• a second communication system that is wireless, said second controller being configured to communicate with the first controller of the device and to program operating parameters of the first controller;
• and
• a support for the device.
