Muscular training apparatus with suction cup and handle - has cup moving in relation to supporting surface in common housing against spring action

摘要

The apparatus has a suction cup (5) elastically coupled to a handle (7), and a supporting surface for the cup. The cup and surface are movable in relation to each other in a common housing (1), and a spring supported from the housing opposes movement of the cup in the detachment direction. The supporting surface can be formed by a further suction cup (5'), and the housing can be in two or more detachable parts. It can also have one or more external protrusions (3,3'). Alternatively it can be elastic. ADVANTAGE - Trains both white and red muscular fibres.
