## Abstract

An exercise device includes a first exercise bar. The first exercise bar includes a first tube extending from a first end to a second end and defining a cavity, a first weight configured to be selectively received within the first cavity, and a first slow loading mechanism coupled to the first tube proximate the second end and configured to contact the first weight when the first weight is received by the first cavity to provide a friction force to the first weight to slow the loading of the first weight into the first cavity.

## Claims

### Claim 1

An exercise device comprising:
a first exercise bar comprising:
a first tube extending from a first end to a second end and defining a first cavity;
a first weight configured to be selectively received within the first cavity; and
a first slow loading mechanism coupled to the first tube proximate the second end and configured to contact the first weight when the first weight is received by the first cavity to provide a friction force to the first weight to slow the loading of the first weight into the first cavity, the first slow loading mechanism comprising:
a body defining a slow loading cavity, the body having a first groove including a plurality of apertures; and
a ring coupled to the body such that the ring is at least partially located within the first groove, the ring including a plurality of grip members, each grip member received by at least one aperture of the plurality of apertures and extending at least partially into the slow loading cavity to contact the first weight when the first weight is received by the first cavity.

### Claim 2 (depends on 1)

The exercise device of claim 1, further comprising:
a second exercise bar comprising:
a second tube extending from a third end to a fourth end and defining a second cavity, the second tube configured to selectively couple to the first tube proximate the first and third ends;
a second weight configured to be selectively received within the second cavity; and
a second slow loading mechanism coupled to the second tube proximate the fourth end and configured to contact the second weight when the second weight is received by the second cavity to provide a friction force to the second weight to slow the loading of the second weight into the second cavity.

### Claim 3 (depends on 2)

The exercise device of claim 2, wherein the body is a first body, the slow loading cavity is a first slow loading cavity, the ring is a first ring, the plurality of apertures is a plurality of first apertures, and the plurality of grip members is a plurality of first grip members, and wherein the second slow loading mechanism comprises:
a second body defining a second slow loading cavity, the second body having a second groove including a plurality of second apertures; and
a second ring coupled to the second body such that the second ring is at least partially located within the second groove, the second ring including a plurality of second grip members, each second grip member received by at least one second aperture of the plurality of second apertures and extending at least partially into the second slow loading cavity to contact the second weight when the second weight is received by the second cavity.

### Claim 4 (depends on 1)

The exercise device of claim 1, wherein the first weight includes a second groove, and wherein the grip members are configured to not contact a surface of the second groove of the first weight when the first weight is received by the first cavity.

### Claim 5 (depends on 1)

The exercise device of claim 1, wherein the first exercise bar further comprises a second weight selectively coupled to the first weight.

### Claim 6 (depends on 1)

The exercise device of claim 1, wherein the first tube is tapered between the first end and the second end such that an outer diameter of the first tube decreases from the first end to the second end.

### Claim 7

An exercise device comprising:
a first tube extending from a first end to a second end and defining a first cavity;
a second tube extending from a third end to a fourth end and defining a second cavity, the second tube configured to selectively couple to the first tube proximate the first and third ends;
a first weight configured to be selectively received within the first cavity;
a second weight configured to be selectively received within the second cavity;
a first slow loading mechanism coupled to the first tube and configured to slow the loading of the first weight into the first cavity, the first slow loading mechanism including a first ring having a plurality of first grip members;
a second slow loading mechanism coupled to the second tube and configured to slow the loading of the second weight into the second cavity, the second slow loading mechanism including a second ring having a plurality of second grip members;
a first end cap selectively coupled to the first weight and the first tube; and
a second end cap selectively coupled to the second weight and the second tube.

### Claim 8 (depends on 7)

The exercise device of claim 7, further comprising:
a third weight selectively coupled to the first weight; and
a fourth weight selectively coupled to the second weight.

### Claim 9 (depends on 7)

The exercise device of claim 7, wherein the first slow loading mechanism and the second slow loading mechanism are configured to slow the loading of a respective weight by friction.

### Claim 10 (depends on 7)

The exercise device of claim 7, wherein the first slow loading mechanism and the second slow loading mechanism both include a body configured to hold the respective ring in place within the respective tube.

### Claim 11 (depends on 7)

The exercise device of claim 7, wherein the first weight is configured to screw into the first end cap, and wherein the first end cap is configured screw into the first tube after the first weight is inserted into the first tube.

### Claim 12 (depends on 7)

The exercise device of claim 7, wherein an outer diameter of the first tube at the first end is a first diameter, and wherein an outer diameter of the first tube at the second end is a second diameter, wherein the second diameter is less than the first diameter.

### Claim 13

An exercise device comprising:
a first exercise bar comprising:
a first tube extending from a first end to a second end and defining a first cavity;
a first weight configured to be selectively received within the first cavity; and
a first slow loading mechanism coupled to the first tube proximate the second end and configured to slow the loading of the first weight into the first cavity, the first slow loading mechanism including a ring having a plurality of grip members.

### Claim 14 (depends on 13)

The exercise device of claim 13, wherein the first tube is tapered between the first end and the second end such that an outer diameter of the first tube decreases from the first end to the second end.

### Claim 15 (depends on 14)
