Abstract
A swing exerciser especially suitable for golf exercise uses a handle and cord arranged to move a resistance trolley down a track positioned on the golfer's back swing side. A spring and pulley arrangement resists movement of the trolley down the track, and movement of the handle by the golfer through the curve of a golf swing forces the trolley down the track so that the golf exerciser must overcome the resistance while swinging the handle to strengthen the muscles needed for powerfully hitting a golf ball.
Claims38
A golf swing exerciser comprising:
- a) a resistance cord attached to a golf handle so that a golfer can move the handle through a curve of a simulated golf swing against resistance applied to the handle via the cord;
- b) the cord extending over a pulley arranged on a moveable trolley that is biased upward;
- c) the cord extending from the pulley to a fixed region below a predetermined range of travel of the trolley;
- d) the pulley, cord, and trolley being arranged relative to the curve followed by the handle during the simulated golf swing so that the handle moves away from the trolley as the simulated golf swing proceeds, causing the handle to pull the cord over the trolley pulley as the swing proceeds;
- e) movement of the cord over the pulley during the simulated golf swing being arranged to force the trolley downward against the bias to resist movement of the cord and of the handle for exercise purposes;
- and
- f) the trolley being arranged to move along a track positioned relative to the curve of the golf swing so that the curve moves farther away from the trolley and the track as the swing proceeds toward a hitting region, and this increases movement of the trolley and increases cord resistance as the swing approaches the hitting region.

A golf exerciser comprising;
- a) a run arranged on a swing side of a golfer in a golf stance to extend from above and behind the golfer's shoulders downward to forward and below the golfer's hips;
- b) a runner moveable downward along the run from an upper region of the run to a lower region of the run;
- c) a bias arranged to resist movement of the runner downward along the run and to return the runner upward along the run from any downward position;
- d) a pulley arranged on the runner;
- e) a cord extending from an exercising end of a golf handle over the pulley on the runner and downward to a fixed region of the run;
- and
- f) the run, runner, bias, pulley, cord, and handle being arranged so that as the golfer moves the handle through a simulated golf swing, the handle pulls the cord over the pulley and draws the runner downward along the run against the resistance of the bias.
4 more elements
A swing exerciser comprising;
- a) a run configured to form a line and a runner arranged to move along the run;
- b) a spring arranged to bias the runner toward a starting end region of the run so that the spring resists movement of the runner along the run to a finishing end region of the run;
- c) a pulley arranged on the runner to move with the runner;
- d) a cord extending from the finishing end region of the run over the pulley on the runner and to a swing handle arranged to move in a curved swing path beginning near the runner at the starting end region of the run and curving away from the run so that movement of the handle pulls the cord away from the run, which pulls the runner along the run from the starting position to the finishing position against the bias of the spring;
- and
- e) the bias applied by the spring to the runner during the swing of the handle being transmitted to the handle from the cord over the pulley on the runner so that a line of resistance applied by the cord to the handle moves from the starting end region of the run to the finishing end region of the run as the swing progresses.

The swing exerciser of claim 26, including a selectable plurality of the springs connectable to the runner via the block and tackle.
A method of applying a variable resistance to a simulated golf swing for exercise purposes, the method comprising:
- a) arranging a cord to extend from a golf handle over a pulley on a trolley and downward to a fixed region so that when a golfer moves the handle through a simulated golf swing the handle moves away from the trolley and pulls the cord over the trolley pulley to draw the trolley downward along a track;
- b) upwardly biasing the trolley against downward movement along the track;
- and
- c) arranging the cord and trolley relative to a curve followed by the handle during the simulated golf swing so that movement of the handle causes increased movement of the trolley as the swing proceeds from a back swing region to a hitting region, and the increased movement of the trolley as the swing proceeds applies increasing resistance to the swing as the swing approaches the hitting region.
1 more element
In a golf swing exerciser using a resistance cord attached to a golf handle so that a golfer can move the handle through a curve of a simulated golf swing against resistance applied to the handle via the cord, the improvement comprising;
- a) the cord being operatively connected to a moveable runner so that movement of the cord during the simulated golf swing causes the runner to move;
- b) the runner being biased to resist movement during the simulated golf swing and thereby apply resistance to the cord moving the runner so that the cord resists movement of the handle;
- and
- c) the cord and runner being arranged so that cord resistance applied to the handle during the simulated golf swing increases in force as the simulated golf swing proceeds from a back swing region to a hitting region.
1 more element
A golf swing exerciser comprising:
- a) a resistance applied to a golf handle so that a golfer can move the handle through a curve of a simulated golf swing against the resistance;
- b) a pair of cords attached to the golf handle and extending to respective pulleys on respective moveable trolleys arranged to run along a track;
- c) a fixed end of the lower-one of the cords being secured below a lower one of the trolleys, and a pulley block being interposed between a fixed end of an upper one of the cords and a pulley on the upper one of the trolleys so that as the handle pulls the cords away from the track while following the curve of the golf swing, the cords pull the lower trolley downward farther than the upper trolley is moved downward;
- d) each of the trolleys being biased against downward movement;
- and
- e) the curve of the golf swing being arranged relative to the trolley track so that the cords are pulled more rapidly away from the track as the swing approaches a hitting region to result in greater resistance applied to the handle as the simulated golf swing approaches the hitting region.
