To provide a training apparatus for effective and safe performance of KAATSU training. A training apparatus is made up of a tight fitting band 100, a main device 200, a measuring segment 300, and a control segment 400. The tight fitting band 100 is wrapped around a predetermined region of a limb. The tight fitting band 100 has an air-tight inflatable bag. The compression force applied to the limb can be varied by supplying the air to and removing the air from the inflatable bag. The main device 200 controls the supply and removal of the air into and from the inflatable bag. The measuring segment 300 is attached to the limb around which the tight fitting band 100 is wrapped to measure the magnitude of a pulse wave. The control segment 400 determines, in preprocessing performed before the KAATSU training, the pulse wave component at a time point at which the magnitude of the pulse wave reaches the maximum, and chooses, as an appropriate gas pressure, the pressure within the inflatable bag that is produced at a time point at which such a pulse wave is generated that is obtained by means of multiplying the pulse wave component at a time point at which the magnitude of the pulse wave reaches the maximum with a numeral equal to or larger than 0. 2 but smaller than 1.
