Abstract
A weight resistance exercise machine having cable and pulley linkage assemblies attached to a single weight stack. Each cable and pulley linkage assembly, which is independent of the other(s), can be used by one arm or leg during bilateral exercise training (that is, training in which both limbs of a pair are used to simultaneously to lift a weight). A tilt platform and biofeedback assembly display and measure in real-time how much each limb of a pair is contributing to such lifting effort.
Claims14
An exercise assembly comprising:
- a) a frame;
- b) a single resistance source;
- c) a tilt platform pivotally attached to said single resistance source;
- d) a first pulley connected to said frame;
- e) a second pulley connected to said tilt platform;
- f) a first cable disposed around said first and second pulleys and connected to said frame;
- g) a third pulley connected to said frame;
- h) a fourth pulley connected to said tilt platform;
- and
- i) a second cable disposed around said third and fourth pulleys and connected to said frame.
An exercise assembly comprising:
- a) a frame;
- b) a single load;
- c) a tilt platform pivotally attached to said single load;
- d) a first linkage assembly comprising:
- i) a first pulley connected to said frame;
- ii) a second pulley connected to said tilt platform;
- e) a first cable having a distal end and a proximate end, wherein said distal end is anchored to said frame, and said first cable is disposed around said first and second pulleys of said first linkage assembly;
- f) a second linkage assembly comprising:
- i) a third pulley connected to said frame;
- ii) a fourth pulley connected to said tilt platform;
- and
- g) a second cable having a distal end and a proximate end, wherein said distal end is anchored to said frame, and said second cable is disposed around said third and fourth pulleys of said second linkage assembly.
A method for determining relative contributions of a first limb and a second limb simultaneously imparting lifting force on a single resistance source comprising:
- a) pulling on a proximate end of a first cable of an exercise assembly with said first limb, wherein said exercise assembly comprises:
- i) a frame, wherein said single resistance source is disposed on said frame;
- ii) a tilt platform pivotally attached to said single resistance source;
- iii) a first pulley connected to said frame;
- iv) a second pulley connected to said tilt platform, wherein said first cable has said proximate end and a distal end, said first cable is disposed around said first and second pulleys, and said distal end of said first cable is connected to said frame;
- v) a third pulley connected to said frame;
- vi) a fourth pulley connected to said tilt platform;
- and
- vii) a second cable, wherein said second cable has said proximate end and a distal end, said second cable is disposed around said third and fourth pulleys, and said distal end of said second cable is connected to said frame;
- b) simultaneously pulling on a proximate end of said second cable with said second limb;
- and
- c) observing relative contributions of said first and second limbs in lifting said single resistance source based on the amount of tilt of said tilt platform from a horizontal orientation.
