• The problem to be solved:
  The main aim was to develop a general use, body-building and physical training device for the sportsmen of heavy sports (field and heavy athletics, weight lifting, boxing, wrestling, etc.).

• Definition:
  The invention is a physical training device that makes possible the safe weight lifting using heavier weights than the usual ones. The vertebral column is loaded only by a vertical compressive force and the device highly reduces the risk of injuries. It is also suitable to develop those muscular tracts that can not be done using the traditional devices.

• Presentation:
  The physical training device consists of an annular body, two handles, four legs and the applied weights (see Figure 1.). The distance between the handles and their height above the body can be adjusted. The handles can also be turned round during the lifting of the weights. During the weight lifting the lifting person stands inside the annular body and, this way, he/she is located just in the centre of gravity of the device (see Figure 2.). This is why his/her vertebral column becomes loaded only by a vertical compressing force. This way, the design of the device makes also possible the lifting of weights that are much heavier than the usual ones, without the risk of injury. During its use, the centre of gravity of the device is always situated below or just above the knees and below the holding point. By replacing the two handles, both pulling and pushing exercises can also be made, respectively.

Usage variations

With fix pulling-lifting arms.     With adjustable pulling-lifting arms.    With adjustable pushing-lifting arms.

• Application:
  The physical training device can be used in fitness saloons, sports establishments, at home, in physical-strength demonstration competitions and in remedial gymnastics for rehabilitation purposes.

• Advantages:
  This device makes also possible to lift weights that are 50% to 100% heavier than the usual ones.
  It is suitable to strengthen also such muscular tracts and fibres that are required by a given sports activity and which can not be achieved with the use of the traditional training devices.
  It makes also possible to equilibrate the asymmetry of the muscular forces in both sides of the body.
  It highly reduces the risk of injury during weight lifting.

• Stage of development:
  Various devices have already been built and are in use.
