Exercise device with springs

Abstract

An exercise device comprises a bar, a compression spring and a handgrip, wherein the handgrip abuts the compression spring. The handgrip is axially rotatable around the bar and is movable along the length of the bar. Upon performing an exercise, a user may rotate the handgrip while exerting lateral force on the handgrip, and consequently pushing the compression spring either inward or outward. In an embodiment, a weight may be added to add resistance by weight in addition to resistance by spring. In another embodiment, the exercise device may be connected to another exercise device or a plurality of exercise devices comprising the same elements. Depending on the user's skill, physical strength and particular exercise regime, the user may use a single compression spring or multiple compression springs, and either no weight, a single weight or multiple weights, to provide simultaneous training of different muscle groups in a single exercise.

What is claimed is: 
     
         1 . An exercise device comprising:
 a bar;   a compression spring; and   a handgrip axially rotatable around the bar, wherein the compression spring abuts the handgrip and is laterally movable along the bar upon being exerted by force.   
     
     
         2 . The exercise device of  claim 1 , further comprising a weight. 
     
     
         3 . The exercise device of  claim 1 , further comprising a locking device to secure the compression spring. 
     
     
         4 . The exercise device of  claim 1 , further comprising a first connector that mates with a second connector of a second exercise device. 
     
     
         5 . The exercise device of  claim 1 , further comprising a second bar, a second compression spring and a second handgrip that is axially rotatable around the second bar, wherein the second compression spring abuts the handgrip and is laterally movable along the second bar upon being exerted by force. 
     
     
         6 . The exercise device of  claim 5 , further comprising a first connector and a second connector that mate the first bar and the second bar. 
     
     
         7 . The exercise device of  claim 1 , further comprising a plurality of bars, a plurality of compression springs and a plurality of handgrips. 
     
     
         8 . The exercise device of  claim 4 , wherein the first connector further comprises an externally threaded male portion and the second connector further comprises an internally threaded female portion. 
     
     
         9 . An exercise device comprising:
 an elongated bar further comprising a plurality of compression springs and a plurality of handgrips abutting the plurality of compression springs, wherein the plurality of handgrips and the plurality of compression springs are laterally movable along the elongated bar upon being exerted by a force, and wherein the elongated bar is detachable at a connection point.   
     
     
         10 . The exercise device of  claim 9 , further comprising a connector to attach a first unit and a second unit of the elongated bar at the connection point. 
     
     
         11 . The exercise device of  claim 9 , further comprising a weight. 
     
     
         12 . The exercise device of  claim 9 , further comprising a locking device to secure the plurality of compression springs. 
     
     
         13 . The exercise device of  claim 9 , further comprising a plurality of connection points. 
     
     
         14 . The exercise device of  claim 9 , further comprising a plurality of weights. 
     
     
         15 . The exercise device of  claim 9 , further comprising a plurality of locking devices to secure the plurality of compression springs. 
     
     
         16 . An exercise device comprising:
 a first bar having a first compression spring and a first handgrip; and   a second bar having a second compression spring and a second handgrip, wherein the first bar and the second bar are secured by a connector, and wherein the first compression spring is movable along the first bar and the second compression spring is movable along the second bar.   
     
     
         17 . The exercise device of  claim 16 , further comprising a first locking device to secure the first compression spring and a second locking device to secure the second compression spring. 
     
     
         18 . The exercise device of  claim 16 , further comprising a weight. 
     
     
         19 . The exercise device of  claim 16 , wherein the first handgrip is axially rotatable around the first bar and the second handgrip is axially rotatable around the second bar. 
     
     
         20 . The exercise device of  claim 16 , further comprising a first weight and a second weight.
