## Background
BACKGROUND OF THE INVENTION
Physical exercise is beneficial to human health in many way including, for example, improved circulation, increased immunity, greater physical strength, and endurance. Resistance and flexibility training exercises help develop muscle tone while providing other valuable health benefits.
Typically, elastic bands and surgical tubing are used for resistance exercise and physical therapy. There are numerous complaints about the bands and tubes digging into or burning the user's hands, feet, and back. Some devices include handles, but it may be difficult to insert a foot or a hand through the handle. In addition, resistance cords can easily slip off a foot or a hand and become a safety hazard.
Plantar fasciitis is a problem that affects millions of people and can be quite debilitating. Everyday activities, for example, walking and standing can be are very painful. Plantar fasciitis is often treated by stretching the plantar fascia, the soleus, the gastrocnemius muscles of the lower leg, or a combination thereof.
What is needed is a resistance exercise and physical therapy apparatus that can be used for Pilate's exercises or for physical therapy of conditions such as Plantar fasciitis.
SUMMARY OF THE INVENTION
The present invention provides a resistance exercise and physical therapy apparatus in the form of an elongate resilient member that has significant advantages over the existing devices. For example, a toe hold on the elongate resilient member allows for a greater number of exercise movements without fear that the elongate resilient member will slide off the foot and hit the user. By engaging the bones instead of the skin, the elongate resilient member can be stretched at higher tensions without burning the skin between the user's toes. Further, the elongate resilient member with a novel toe hold cannot easily be dislodged. This allows for a wide variety of novel stretches and moves not possible or safe with the existing bands, tubes, strapped cords, or bolo cords. Further, an elongate resilient member with a ball on the end is not comfortable or stable to grasp by the toes because it affects the balance of the user when standing. On the other hand, the resistance exercise and physical therapy apparatus, as provided by the present invention, has a unique shape that allows for the user to comfortably stand and be held by the toes. However, unlike a bolo device, which has a large mass on the terminal ends and is harder to grasp, the resistance exercise and physical therapy apparatus is very easy to grasp with the minimal mass at the terminal ends.
The present invention also provides a resistance exercise and physical therapy apparatus in the form of an elongate resilient member that is specially molded resistance cord to be easily grasped by the user's toes, for example, between the big toe and the second toe. Additionally, the elongate resilient member has spaced molded thickenings. The thickenings act as stops for the elongate resilient member. In one embodiment, one end of the cord is grasped by the foot and the other end is grasped by the hand. This design allows cord to be squeezed in the webbing between the stricture created by the flesh and bones of the thumb and index fingers or by the flesh and bones of the hand grasping the molded thickenings. The toe grasping portions of the elongate resilient member are widened and flattened on the bottom so that the user may stand comfortably grasping the cord between their toes, with their feet flat on the floor. In this manner, the toe grasping portion does not affect the balance of the user. Further, the user may adjust the height and the tension of the resistance exercise and physical therapy apparatus by grasping the elongate resilient member at various thickenings. The spaced balls provide an improved means of grasping the elongate resilient member, as they provide a slip-proof means of holding the elongate resilient member.
The present invention provides a resistance exercise and physical therapy apparatus. The resistance exercise and physical therapy apparatus includes: an elongate resilient member having a proximal end and a distal end, wherein the elongate resilient member includes an elastic material with a first enlargement at the proximal end, a second enlargement at the distal end, and one or more spaced-apart third enlargements along the length of the elongate resilient member, wherein the first enlargement is grasped by a first foot of a human user or by one or more floor or wall mounted sockets.

DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a resistance exercise and physical therapy apparatus in the form of an elongate resilient member that has significant advantages over the existing devices. For example, a toe hold on the elongate resilient member allows for a greater number of exercise movements without fear that the elongate resilient member will slide off the foot and hit the user. By engaging the bones instead of the skin, the elongate resilient member can be stretched at higher tensions without burning the skin between the user's toes. Further, the elongate resilient member with a novel toe hold cannot easily be dislodged. This allows for a wide variety of novel stretches and moves not possible or safe with the existing bands, tubes, strapped cords, or bolo cords. Further, an elongate resilient member with a ball on the end is not comfortable or stable to grasp by the toes because it affects the balance of the user when standing. On the other hand, the resistance exercise and physical therapy apparatus, as provided by the present invention, has a unique shape that allows for the user to comfortably stand and be held by the toes. However, unlike a bolo device, which has a large mass on the terminal ends and is harder to grasp, the resistance exercise and physical therapy apparatus is very easy to grasp with the minimal mass at the terminal ends.
The present invention also provides a resistance exercise and physical therapy apparatus in the form of an elongate resilient member that is specially molded resistance cord to be easily grasped by the user's toes, for example, between the big toe and the second toe. Additionally, the elongate resilient member has spaced molded thickenings. The thickenings act as stops for the elongate resilient member. In one embodiment, one end of the cord is grasped by the foot and the other end is grasped by the hand. This design allows cord to be squeezed in the webbing between the stricture created by the flesh and bones of the thumb and index fingers or by the flesh and bones of the hand grasping the molded thickenings. The toe grasping portions of the elongate resilient member are widened and flattened on the bottom so that the user may stand comfortably grasping the cord between their toes, with their feet flat on the floor. In this manner, the toe grasping portion does not affect the balance of the user. Further, the user may adjust the height and the tension of the resistance exercise and physical therapy apparatus by grasping the elongate resilient member at various thickenings. The spaced balls provide an improved means of grasping the elongate resilient member, as they provide a slip-proof means of holding the elongate resilient member.

In the claims provided herein, the steps specified to be taken in a claimed method or process may be carried out in any order without departing from the principles of the invention, except when a temporal or operational sequence is explicitly defined by claim language. Recitation in a claim to the effect that first a step is performed then several other steps are performed shall be taken to mean that the first step is performed before any of the other steps, but the other steps may be performed in any sequence unless a sequence is further specified within the other steps. For example, claim elements that recite “first A, then B, C, and D, and lastly E” shall be construed to mean step A must be first, step E must be last, but steps B, C, and D may be carried out in any sequence between steps A and E and the process of that sequence will still fall within the four corners of the claim.
Furthermore, in the claims provided herein, specified steps may be carried out concurrently unless explicit claim language requires that they be carried out separately or as parts of different processing operations. For example, a claimed step of doing X and a claimed step of doing Y may be conducted simultaneously within a single operation, and the resulting process will be covered by the claim. Thus, a step of doing X, a step of doing Y, and a step of doing Z may be conducted simultaneously within a single process step, or in two separate process steps, or in three separate process steps, and that process will still fall within the four corners of a claim that recites those three steps.
Similarly, except as explicitly required by claim language, a single substance or component may meet more than a single functional requirement, provided that the single substance fulfills the more than one functional requirement as specified by claim language.
All patents, patent applications, publications, scientific articles, web sites, and other documents and materials referenced or mentioned herein are indicative of the levels of skill of those skilled in the art to which the invention pertains, and each such referenced document and material is hereby incorporated by reference to the same extent as if it had been incorporated by reference in its entirety individually or set forth herein in its entirety. Additionally, all claims in this application, and all priority applications, including but not limited to original claims, are hereby incorporated in their entirety into, and form a part of, the written description of the invention.
Applicants reserve the right to physically incorporate into this specification any and all materials and information from any such patents, applications, publications, scientific articles, web sites, electronically available information, and other referenced materials or documents. Applicants reserve the right to physically incorporate into any part of this document, including any part of the written description, the claims referred to above including but not limited to any original claims.
