The invention provides body-building and rehabilitating equipment for training hand strength. The body-building and rehabilitating equipment for training the hand strength comprises an annular tube, elastic components and telescopic devices, wherein each telescopic device comprises a telescopic airbag, an air pipe, an air pump and a deflation valve; the elastic components and the telescopic airbags are positioned inside the annular tube; the elastic components and the telescopic airbags are connected at intervals to form a ring; the end parts of the elastic components are connected with the end parts of the telescopic airbags; the quantity of the elastic components is equal to that of the telescopic airbags; the air pumps are positioned outside the annular tube; the air pipes run through the annular tube; the telescopic airbags are communicated with the air pumps through the air pipes; the deflation valves are arranged on the air pump. The body-building and rehabilitating equipment fortraining the hand strength not only can exercise the hand strength and the hand flexibility, but also makes hand exercise more interesting; meanwhile, multiple people can participate in the exerciseand interact with one another, so that the exercise is not boring, and people can easily persist in the exercise, thereby achieving expected rehabilitating and body-building effects.
