An exercise machine includes a dual fiilcrum articulated force lever having first and second force arms.

A movable end of the second force arm is pivotally connected to a first end of the first force arm for pivoting of the first force arm about a second fulcrum.

A force arm (10) is slidably attached to the movable mount and a sensor (11) attached to both the force arm and the movable mount such that the sensor detects a force applied to the force arm.

The force arm unit (20) includes two or more rod-like force arms whose intersecting portion is a rotatable pivot.

A resistance load is adjustably attached to the first force arm.

A load linkage connects a seat assembly to the first force arm such that the first force arm moves against the weight of a person.

The limb (9) which elastically presses against the mouth of the lying spout (2) advantageously forms the load arm (13) of a rocker-type element (11) comprising a load arm (13) and a power arm (14).

In the present utility model the arm of force is lengthened according to the leverage principle.

The cylinder bore extends transversally, particularly perpendicularly with respect to the force arm (2).

Regulating devices (28, 29) or actuators are arranged on the respective power arms of the levers.

Said aim is achieved by hingedly connecting two lever arms to a single ram and connecting the force arms to a tractive or pressing device.

The contact point at which the force of the pressure cylinder is transmitted to the force arm is in this case situated outside the inner space of the mill.

The toggle press further comprises at least two lever elements which are rotatably mounted on the frame and each of which has a force arm and a load arm that is hingedly connected to the pressure lever.

He fills your feet with dance and your arms with strength.

The invention relates to a portable test lever comprising a work arm and a force arm for efficient examination of the drive capacity and/or an acceleration capacity of a lift.
