A physical training system includes a belt having a belt attachment member and a first band attachment loop for an elastomeric belt. The belt attachment member is moveably positioned on the belt and at least partially encircles the belt. The belt 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 belt 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 belt attachment member.

A lightweight, portable leg strengthening apparatus includes a footplate and calf support which form a leg rest, a top a friction free sliding element running longitudinally along and supported on a rectangular base. The leg rest is hinged at its attachment to the sliding element to allow a longitudinal tilting movement. The leg rest has adjustability at the hinge point at the ankle to enable alterations in the foot position. The apparatus uses resistance material/rubber cords or springs attached via a plate to a steel cable, travelling via an aperture in the end of the device to the back of the sliding element a top the body of the device to create tension as the leg rest a top the sliding element is moved longitudinally along the body of the device. Resistance can be varied and progressed by using different numbers of resistance cords/springs.

In an exercising band and an exercising monitoring system having the exercising band, the exercising band includes a band part, at least one sensor part and a spacer. The band part is configured to be elongated according as an external force is applied. The sensor part is disposed inside of the band part, is configured to be elongated according as the band part is elongated, and has first and second sensors. The first and second sensors have conductivity. The spacer is configured to insulate the first and second sensors with each other. The first and second sensors are electrically contacted with each other, as the external force is applied along a direction substantially crossing an extending direction of the first and second sensors.

A device for training and rehabilitation of a limb is provided. The device provides a board with a plurality of movement tracks to allow for controlled movement of the limb in various directions. Blockers and other controlling structures may be arranged on the device to limit range of motion of the movement of the limb.

An exercise apparatus for performing push-up type exercises includes an elongate planar surface with at least one transverse slot and a pair of handles movably carried in the transverse slot. The pair of handles are adapted for gripping by a user during performance of the push-up type exercise. The handles are interconnected by a resistance band for providing a selected resistance to resist a laterally outward displacement of the pair of handles during a push-up. A pair of adjustable legs support the apparatus in inclined orientation and a declined orientation, relative to a supporting ground surface. The legs may be attached by a pivot and are movable between a stowed position and an upright supporting position.

A method is provided for preventing back injuries related to sport motions or swings that includes setting an attachment height of a distal end of an elastic of a warmup and training device, the attachment height set to define an angle α backwards from vertical above center of a practice motion specific to a sport to be practiced, attaching a handle to a proximal end of the elastic where a type of the handle corresponds to the sporting activity to be performed, performing the practice motion while holding the handle and stretching the elastic, and returning to the beginning of the practice motion to repeat the activity.

A fitness chair for utilizing exercise resistance bands for a safe full body workout is disclosed. The fitness chair includes a chair frame having a seat member and a backrest member; a first hollow member coupled to the chair frame, the first hollow having a first exercise resistance band passing therethrough; a base frame engaging with the chair frame via one or more chair legs, the base frame having a second hollow member and a third hollow member running parallel therebetween, the second hollow member having a second exercise resistance band passing therethrough, and the third hollow member having a third exercise resistance band passing therethrough.

An arm-training device, and methods of making and using such an arm-training device, whereby the arm-training device includes a flexible elongate member having an elastic length disposed between opposing first and second ends; a first loop formed proximate the first end; a second loop formed proximate the second end; a first slide coupled to the first loop, the first slide movable along the length of the elongate member; and a second slide coupled to the second loop, the second slide movable along the length of the elongate member.
