Patent attributes
An exercise device for compression exercises is adjustable in height and in compression force. The device includes a central housing and a plurality of plungers extending from a top side. A support member is attached to the housing on a bottom side. The support member is movable longitudinally relative to the housing and plungers from a fully retracted position to a fully extended position and is lockable in a plurality of intermediate longitudinal positions to vary the height of the device. Each plunger is operatively associated with an internal bias member that biases the plunger away from the housing. Resistance force on a plunger is adjustable via changing tension of the associated bias member with an adjustment knob to finely adjust tension. An installed bias member is removable and replaceable with a different bias member to coarsely adjust tension.
