## Abstract

An aquatic exercise apparatus for applying a resistive force to an exercising swimmer, the apparatus includes a bracket mounted to a vertically oriented surface located above a pool of water, a container, an operational assembly comprising at least one upper pulley attached to the bracket and at least one lower pulley attached to the container, a cord passing through the at least one upper pulley and the at least one lower pulley, and a fastener configured to attach to an exercising swimmer, where the fastener is attached to a free end of the cord, and where pulling the free end of the cord moves the container upward against gravity.

## Claims

### Claim 1

An aquatic exercise apparatus for applying a resistive force to an exercising swimmer, the aquatic exercise apparatus comprising:
a bracket mounted to a vertically oriented surface located above a pool of water;
a container;
an operational assembly comprising at least one upper pulley attached to the bracket and at least one lower pulley attached to the container,
a cord passing through the at least one upper pulley and the at least one lower pulley, and
a fastener configured to attach to an exercising swimmer, wherein the fastener is attached to a free end of the cord;
wherein pulling the free end of the cord moves the container upward against gravity; and
wherein the aquatic exercise apparatus further comprises a plate attached to the bracket, wherein the plate defines an elongated opening configured to receive a second at least one elastic cord that is attached to the fastener.

### Claim 2 (depends on 1)

The aquatic exercise apparatus of claim 1 wherein the bracket is L-shaped.

### Claim 3 (depends on 1)

The aquatic exercise apparatus of claim 1 wherein the bracket is L-shaped, and is mounted to the vertically oriented surface via an adjustable clamp.

### Claim 4 (depends on 1)

The aquatic exercise apparatus of claim 1 wherein the bracket defines a circular opening at a distal end of the bracket, said circular opening being configured to receive a pullup bar.

### Claim 5

An aquatic exercise apparatus for applying a resistive force to an exercising swimmer, the aquatic exercise apparatus comprising:
an L-shaped bracket mounted to an object located above a pool of water, wherein the L-shaped bracket is mounted to the object via an adjustable clamp;
a container configured to hold a liquid substance or a solid substance;
an operational assembly comprising at least one upper pulley attached to the L-shaped bracket and at least one lower pulley attached to the container,
a cord passing through the at least one upper pulley and the at least one lower pulley, and
a fastener configured to attach to an exercising swimmer, wherein the fastener is attached to a free end of the cord;
wherein pulling the free end of the cord moves the container upward against gravity; and
wherein the container is located above the pool of water.

### Claim 6 (depends on 5)

The aquatic exercise apparatus of claim 5 wherein the L-shaped bracket defines a circular opening at a distal end of the L-shaped bracket, said circular opening being configured to receive a pullup bar.

### Claim 7

An aquatic exercise apparatus for applying a resistive force to an exercising swimmer, the aquatic exercise apparatus comprising:
a bracket mounted to a vertically oriented surface located above a pool of water;
a container;
an operational assembly comprising at least one upper pulley attached to the bracket and at least one lower pulley attached to the container,
a cord passing through the at least one upper pulley and the at least one lower pulley, and
a fastener configured to attach to an exercising swimmer, wherein the fastener is attached to a free end of the cord;
wherein pulling the free end of the cord moves the container upward against gravity; and
wherein the bracket defines a circular opening at a distal end of the bracket, said circular opening being configured to receive a pullup bar.
