## Abstract

An assisted chin/dip exercise apparatus has a main frame and an assist or foot bar pivotally mounted on the frame and linked to a weight stack or resistance for assisting a user standing on the foot bar during performance of chin and dip exercises. The main frame has a first, overhead handle assembly and a second, dip handle assembly below the first handle assembly. The first handle assembly includes a pair of adjustably mounted handles freely pivotable between a first, chin-up position in which the handles extend towards one another at a rearward angle with a small spacing between the handles and a second, pull-up position in which the handles extend in a forward direction and are spaced apart by a larger spacing sufficient to provide head clearance for a user stepping onto the foot bar or while performing a dip exercise.

## Claims

### Claim 1

An exercise machine, comprising:
a frame;
a dipping bar connected to the frame;
an overhead support connected to the frame;
a left gripping assembly connected to the overhead support; and
a right gripping assembly connected to the overhead support,
wherein each of the left and right gripping assemblies comprise:
a non-rotating outwardly extending arm, and
a rotating inwardly extending arm.

### Claim 2 (depends on 1)

The exercise machine of claim 1, wherein the left and right gripping assemblies are mirror images of one another.

### Claim 3 (depends on 1)

The exercise machine of claim 1, wherein the rotating inwardly extending arm on the left gripping assembly and the rotating inwardly extending arm on the right gripping assembly are rotatable between parallel and perpendicular positions with respect to one another.

### Claim 4 (depends on 1)

The exercise machine of claim 1, wherein each rotating inwardly extending arm is freely rotatable and does not lock into position.

### Claim 5 (depends on 1)

The exercise machine of claim 1, wherein the rotating inwardly extending arms each rotate between first and second horizontal positions, the first and second horizontal positions being perpendicular to one another.

### Claim 6 (depends on 1)

The exercise machine of claim 1, wherein the rotating inwardly extending arms are each freely rotatable upwardly and forwardly.

### Claim 7 (depends on 1)

The exercise machine of claim 1, wherein each rotating inwardly extending arm rotates 180 degrees between a first horizontal position and a second horizontal position.

### Claim 8 (depends on 1)

The exercise machine of claim 1, wherein the rotating inwardly extending arm rotates between an angled chin-up position wherein the left and right inwardly extending arms are angled to one another and a parallel pull-up position wherein the left and right inwardly extending arms are parallel to one another.

### Claim 9 (depends on 1)

The exercise machine of claim 1, wherein the rotating inwardly extending arms rotate around axes that are perpendicular to one another.

### Claim 10 (depends on 9)

The exercise machine of claim 9, wherein the perpendicular axes are each positioned 30 degrees to a transverse axes across the exercise machine.

### Claim 11 (depends on 1)

The exercise machine of claim 1, further comprising:
a standing support; and
a weight stack, wherein the weight stack provides a variable upwards support when a user stands on the standing support.

### Claim 12 (depends on 1)

The exercise machine of claim 1, wherein the non-rotating outwardly extending arm points straight outwardly from an outer side of the frame.

### Claim 13 (depends on 1)

The exercise machine of claim 1, wherein the non-rotating outwardly extending arm points forwardly and inwardly.

### Claim 14 (depends on 1)

The exercise machine of claim 1, further comprising a textured rock gripping surface on each gripping assembly.

### Claim 15 (depends on 1)

The exercise machine of claim 1, wherein the dipping bar comprises handles that are rotatable between a wide grip position and a narrow grip position.
