Abstract
A leg curl exercise machine includes a frame, a platform supported by the frame along a vertical midplane and a pair of levers pivotally connected to the frame in front of the platform. The forward ends of the levers are adapted to hold removable weights and, during performance of a leg curl exercise, are adapted to be acted upon by the legs of an exerciser supported on the platform. The levers pivot along outer planes of movement that diverge from the front of the frame and tilt inwardly toward the top of the frame, thereby coupling the force applied by the legs against separate weight resistances that move through planes that naturally accommodate the musculoskeletal make-up of a person.
Claims27
A leg curl exercise machine comprising:
- a frame;
- a platform secured to the frame along a vertical midplane;
- a lever pivotally connected to the frame in front of the platform, the lever adapted to hold at least one removable weight at a forward, lower end thereof and adapted to be pivoted upwardly by the back of the leg of an exerciser supported on the platform during the performance of a leg curl, the lever being pivotal in a plane that is non-parallel with respect to the central vertical plane.
A leg curl exercise machine comprising:
- a frame;
- a platform secured to the frame along a vertical midplane;
- a pair of levers pivotally connected to the frame in front of the platform, each lever having a forward end adapted to hold at least one removable weight and adapted to be pivoted upwardly by one leg of an exerciser supported on the platform during the performance of a leg curl, the levers being pivotal in outer planes that are non-parallel with respect to the vertical midplane.
A leg curl exercise machine comprising:
- a frame;
- a platform supported by the frame along a vertical midplane;
- and
- a pair of pivotal levers, each lever having a forward end adapted to hold at least one removable weight and adapted to be acted upon by the leg of an exerciser supported on the platform during the performance of a leg curl, each lever adapted to pivot in an outer plane of movement that diverges from a forward end of the machine.
