Abstract

Cable and power rack exercise machine. An exercise machine may include a frame, a resistance mechanism supported by the frame, a first pull cable and a second pull cable supported by the frame and linked to the resistance mechanism, and a power rack attached to the frame. The power rack may include a first upright post configured to have a first barbell holder adjustably attached thereto and a second upright post configured to have a second barbell holder adjustably attached thereto. The first barbell holder may be adjusted in various positions between a first highest position and a first lowest position on the first upright post. The second barbell holder may also be adjusted in various positions between a second highest position and a second lowest position on the second upright post.

First claim

The invention claimed is:

1. An exercise machine comprising:
a frame;
a resistance mechanism supported by the frame, wherein the resistance mechanism includes:
a motor; or
a flywheel and one or more magnets arranged to selectively resist rotation of the flywheel;

a first pull cable and a second pull cable supported by the frame and linked to the resistance mechanism;
a power rack attached to the frame, the power rack including:
a first upright post configured to have a first barbell holder adjustably attached thereto such that the first barbell holder is configured to be adjusted in various positions between a first highest position and a first lowest position on the first upright post; and
a second upright post configured to have a second barbell holder adjustably attached thereto such that the second barbell holder is configured to be adjusted in various positions between a second highest position and a second lowest position on the second upright post;

a first tensioner spring configured to reduce slack in the first pull cable;
a second tensioner spring configured to reduce slack in the second pull cable;
a first pulley configured to selectively receive the first pull cable to enable the first pull cable to be selectively attached to a barbell to enable the first tensioner spring to hinder a user in lifting the barbell; and
a second pulley configured to selectively receive the second pull cable to enable the second pull cable to be selectively attached to the barbell to enable the second tensioner spring to hinder the user in lifting the barbell.

2. The exercise machine of claim 1 , wherein:
the first tensioner spring is configured to provide between 3-5 pounds, between 2-8 pounds, between 1-11 pounds, or between 2-20 pounds of force hindering the user in lifting the barbell; and
the second tensioner spring is configured to provide between 3-5 pounds, between 2-8 pounds, between 1-11 pounds, or between 2-20 pounds of force hindering the user in lifting the barbell.

3. The exercise machine of claim 2 , wherein:
the resistance mechanism is configured to be selectively set at one of multiple resistance levels; and
the first pulley and the second pulley enable the resistance mechanism to hinder the user in lifting the barbell in proportion to the set resistance level of the resistance mechanism.

4. The exercise machine of claim 1 , further comprising:
a third pull cable and a fourth pull cable supported by the frame and linked to the resistance mechanism;
a third pulley configured to selectively receive the third pull cable to enable the third pull cable to be selectively attached to the barbell to enable the first tensioner spring to assist the user in lifting the barbell, wherein the first tensioner spring is configured to provide between 3-5 pounds, between 2-8 pounds, between 1-11 pounds, or between 2-20 pounds of force assisting the user in lifting the barbell; and
a fourth pulley configured to selectively receive the fourth pull cable to enable the fourth pull cable to be selectively attached to the barbell to enable the second tensioner spring to assist the user in lifting the barbell, wherein the second tensioner spring is configured to provide between 3-5 pounds, between 2-8 pounds, between 1-11 pounds, or between 2-20 pounds of force assisting the user in lifting the barbell.

5. The exercise machine of claim 1 , wherein the resistance mechanism includes the motor, the exercise machine further comprising:
a third pull cable and a fourth pull cable supported by the frame and linked to the resistance mechanism;
a third pulley configured to selectively receive the third pull cable to enable the third pull cable to be selectively attached to the barbell to enable the motor to assist the user in lifting the barbell; and
a fourth pulley configured to selectively receive the fourth pull cable to enable the fourth pull cable to be selectively attached to the barbell to enable the motor to assist the user in lifting the barbell.

6. The exercise machine of claim 1 , wherein the power rack further includes a pull-up bar supported by the first upright post and by the second upright post.

7. The exercise machine of claim 1 , wherein the power rack further includes:
a first weight plate holder supported by the first upright post; and
a second weight plate holder supported by the second upright post.

8. The exercise machine of claim 1 , further comprising a first spotter arm adjustably attached to the first upright post and a second spotter arm adjustably attached to the second upright post, the first and second spotter arms configured to prevent the barbell from falling on the user if the user is unable to continue lifting the barbell.

9. The exercise machine of claim 1 , further comprising one or more dumbbell racks supported by the frame and each configured to hold a dumbbell.

10. The exercise machine of claim 1 , further comprising a barbell retention mechanism including:
a tube attached to the frame and configured to receive a first end of the barbell; and
a strap attached to the frame and configured to wrap around a second end of the barbell to keep the second end of the barbell positioned against the frame.

11. An exercise machine comprising:
a frame;
a resistance mechanism supported by the frame, wherein the resistance mechanism includes:
a motor; or
a flywheel and one or more magnets arranged to selectively resist rotation of the flywheel;

a first pull cable and a second pull cable supported by the frame and linked to the resistance mechanism;
a power rack attached to the frame, the power rack including:
a first upright post configured to have a first barbell holder adjustably attached thereto such that the first barbell holder is configured to be adjusted in various positions between a first highest position and a first lowest position on the first upright post; and
a second upright post configured to have a second barbell holder adjustably attached thereto such that the second barbell holder is configured to be adjusted in various positions between a second highest position and a second lowest position on the second upright post;

a tube attached to the frame and configured to receive a first end of a barbell; and
a strap attached to the frame and configured to wrap around a second end of the barbell to keep the second end of the barbell positioned against the frame.

12. The exercise machine of claim 11 , further comprising:
a first tensioner spring configured to reduce slack in the first pull cable; and
a second tensioner spring configured to reduce slack in the second pull cable.

13. The exercise machine of claim 12 , further comprising:
a first pulley configured to selectively receive the first pull cable to enable the first pull cable to be selectively attached to the barbell to enable the first tensioner spring to hinder a user in lifting the barbell, wherein the first tensioner spring is configured to provide between 3-5 pounds, between 2-8 pounds, between 1-11 pounds, or between 2-20 pounds of force hindering the user in lifting the barbell; and
a second pulley configured to selectively receive the second pull cable to enable the second pull cable to be selectively attached to the barbell to enable the second tensioner spring to hinder the user in lifting the barbell, wherein the second tensioner spring is configured to provide between 3-5 pounds, between 2-8 pounds, between 1-11 pounds, or between 2-20 pounds of force hindering the user in lifting the barbell.

14. The exercise machine of claim 13 , wherein:
the resistance mechanism is configured to be selectively
