Abstract

A resistance band exercise machine for performing various exercises. An embodiment includes a housing for a cable-pulley variable resistance system. Some embodiments are configured to receive one or more safety bars to set a starting position of an exercise. Some embodiments include a training partner assistantship feature for a training partner to assist the user by imparting a secondary force on the machine. The configuration of the cable-pulley variable resistance system may be in any manner based on the exercise. In some embodiments, a user performs an exercise on the resistance band exercise machine to overcome a primary (e.g., resistance bands) and secondary (e.g., springs) sources of variably increasing resistance from the cable-pulley variable resistance system.

Claims (46)

1 . A resistance member exercise machine, the exercise machine comprising:

a first resistance attachment member secured to a cable-pulley system, wherein the first resistance attachment member is configured to temporarily receive one or more variable resistance members;

the cable-pulley system including a cable operably connected to a user-interaction element through which a user can impart a force to cause the first resistance attachment member to move;

a second resistance attachment member fixed to a base structure of the resistance member exercise machine, wherein the second resistance attachment member is configured to temporarily receive the one or more variable resistance members;

wherein the first resistance attachment member is configured to move away from the second resistance attachment member when force is imparted onto the user-interaction element that is greater than a resistance force of the one or more variable resistance members secured to both the first resistance attachment member and the second resistance attachment member;

a training partner assistantship feature operably connected to the first resistance attachment member, wherein the training partner assistantship feature is configured to allow another user to impart a force onto the first resistance attachment member via the training partner assistantship feature to reduce a total force imparted on the user; and

a negative repetition assistance feature operably connected to the first resistance attachment member, wherein the negative repetition assistance feature is configured to allow another user to impart an additional force onto the first resistance attachment member to increase the total force imparted onto the user.

2 . The machine of claim 1 , further including a guide rail, wherein the first resistance attachment member is configured to translate along a length of a guide rail, the guide rail including:

a first end, a second end, and the length extending therebetween;

at least one safety bar attachment point along the length of the guide rail between the first and second ends of the guide rail;

wherein at least one safety bar reduces a range of motion and sets a starting position of the first resistance attachment member when the at least one safety bar is secured to the at least one safety bar attachment point between the first and second ends of the guide rail.

3 . The machine of claim 2 , further including a secondary resistance member configured to apply a secondary resistance force on the first resistance attachment member when the first resistance attachment member reaches a predetermined distance from the second end of the guide rail.

4 . The machine of claim 3 , wherein the secondary resistance member is one or more springs.

5 . The machine of claim 2 , wherein the guide rail includes a multitude of apertures longitudinally spaced about the length of the guide rail and configured to receive the at least one safety bar.
