Abstract: Apparatus (1) for the physical training of at least one of the limbs (40) of a living being, comprising a cuff (2) comprising an inflatable pouch (3), a device (4) for inflating the pouch (3), a system (5) for venting the pouch (3), a control unit (9) controlling the inflation device (4), said inflatable pouch (3) and the cuff (2) surrounding the pouch (3) being able to be positioned around a limb (40) that is to be trained so as to make it possible, when the pouch (3) is in the inflated state, to reduce the blood circulation through said limb (40). The training apparatus (1) comprises an air reserve (6) connected to the pouch (3) for transfer of air between the pouch (3) and the air reserve (6) at least when the pouch is deformed, and a pressure sensor (7) configured to measure the pressure of the air circuit, at least part of which is formed by the fluidic connection (8) between the inflatable pouch (3) and the air reserve (6).
