## Abstract

A physical training system includes a belt having a back attachment member and a first band attachment loop for an elastomeric belt. The back attachment member is moveably positioned on the belt and at least partially encircles the belt. The back attachment member comprises a first portion and a second portion, the first portion extending completely across a width of the belt on the outer side of the belt, and the second portion extending at least partially across the width of the belt on the inner side of the belt. The first band attachment loop is moveably connected to the back attachment member. The elastomeric band extends through the first band attachment loop. A foot coupling includes at least one flexible strap and a second band attachment loop. The elastomeric band extends between the foot coupling and the back attachment member.

## Claims

### Claim 1

A physical training system configured to be worn on a human body, the physical training system comprising:
a belt defining a width and having an inner side and an outer side, the belt including an adjustment portion;
a back attachment member moveably positioned on the belt and at least partially encircling the belt, the back attachment member comprising a first portion and a second portion, the first portion extending completely across the width of the belt on the outer side of the belt and the second portion extending at least partially across the width of the belt on the inner side of the belt, and the second portion comprising a top flap connected to a top edge of the first portion and a bottom flap connected to a bottom edge of the first portion;
a first band attachment loop moveably connected to the back attachment member;
an elastomeric band extending through the first band attachment loop; and
a foot coupling including at least one flexible strap and a second band attachment loop, wherein the elastomeric band is coupled to the second band attachment loop such that the elastomeric band extends between the foot coupling and the back attachment member.

### Claim 2 (depends on 1)

The physical training system of claim 1, wherein the at least one flexible strap is configured to extend over a dorsal side of a foot of the human body.

### Claim 3 (depends on 2)

The physical training system of claim 2, wherein the flexible strap is connected to a sole of a shoe.

### Claim 4 (depends on 2)

The physical training system of claim 2 wherein the flexible strap is connected to a sock.

### Claim 5 (depends on 1)

The physical training system of claim 1 wherein the first band attachment loop is a first ring and the second band attachment loop is a second ring.

### Claim 6 (depends on 5)

The physical training system of claim 5 wherein the elastomeric band is defined by two opposite ends, wherein a first end is connected to the first ring and a second end is attached to the second ring.

### Claim 7 (depends on 1)

The physical training system of claim 1 wherein the flexible strap extends through the band attachment loop.

### Claim 8 (depends on 1)

The physical training system of claim 1 wherein the top flap and the bottom flap each have a back surface with hook fasteners connected thereto, and the hook fasteners on the back surface of the top and bottom flaps attach to a loop fastener on the inner side of the belt to further secure the back attachment member to the belt.

### Claim 9

A method of physically training a human body for a sport, the method comprising:
positioning a belt on a hip portion of the human body, the belt defining a width and having an inner side and an outer side, the belt including an adjustment portion;
positioning a back attachment member on a rear side of the belt, the back attachment member at least partially encircling the belt, the back attachment member comprising a first portion and a second portion, the first portion extending completely across the width of the belt on the outer side of the belt, and the second portion extending at least partially across the width of the belt on the inner side of the belt, wherein the second portion of the back attachment member comprises a top flap connected to a top edge of the first portion and a bottom flap connected to a bottom edge of the first portion, and wherein positioning the back attachment member on a rear side of the belt comprises moving the first portion to a desired location on the outer side of the belt and joining the top flap and the bottom flap to the inner side of the belt via hook and loop fasteners;
moving a first band attachment loop and an elastomeric band inserted through the first band attachment loop following positioning of the back attachment member on the rear side of the belt, the first band attachment loop pivotably coupled to the back attachment member;
coupling the elastomeric band to a foot of the human body via a flexible article of footwear, the flexible article of footwear including at least one flexible strap and a second band attachment loop, wherein the elastomeric band extends through the second band attachment loop such that the elastomeric band extends between the foot coupling and the back attachment member; and
with the elastomeric band extending between the foot coupling and the back attachment member, moving the human body over a range of movements associated with the sport.

### Claim 10 (depends on 9)

The method of claim 9 wherein the range of movements associated with the sport include running or jogging movements of the human body.

### Claim 11 (depends on 9)

### Claim 12

A physical training system configured to be worn on a human body, the physical training system comprising:
a left flexible article of footwear configured to receive a left foot of the human body, the left flexible article of footwear comprising at least one left strap extending over a dorsal side of the left flexible article of footwear;
a right flexible article of footwear configured to receive a right foot of the human body, the right flexible article of footwear comprising at least one right strap extending over a dorsal side of the right flexible article of footwear;
a belt configured to engage a torso of the wearer, the belt defining a horizontal direction;
a belt coupling coupled to the belt, the belt coupling including a back attachment member coupled to a vertically oriented loop member such that a passage through the loop member is defined in the horizontal direction, the back attachment member moveably positioned on the belt and at least partially encircling the belt, the back attachment member comprising a first portion and a second portion, the first portion extending completely across the width of the belt on the outer side of the belt and the second portion extending at least partially across the width of the belt on the inner side of the belt, the second portion comprising a top flap connected to a top edge of the first portion and a bottom flap connected to a bottom edge of the first portion; and
an elastic resistance band including a first end portion coupled to the at least one left strap, a central portion extending through the loop member on the belt, and a second end portion coupled to the at least one right strap such that the elastic resistance band is configured in an inverted V-shape.

### Claim 13 (depends on 12)

The physical training system of claim 12 wherein the left flexible article of footwear is a sock, and wherein the at least one left strap is a first left strap extending over a fabric panel of the sock from a lateral side to a medial side of the sock.

### Claim 14 (depends on 13)
