The exercise cylinder enables the user to jump, using his own weight, by compressing and releasing fluid or fluids. It consists of a hollow cylinder which is closed at one end. A mobile piston moves inside the cylinder. Supports on the ground can be attached to the piston or the cylinder. Two opposite facing handles, and two foot-rests are fixed to the cylinder for holding on. These can be adjusted to the size of the user. A hole for inserting and pressurising the fluid has a check-valve, adjustable by the user.
