A flexible weight sled includes a main body member made from a flexible material, such as a nylon webbing, canvas, or the like. The main body member includes a weight strap and a rear weight strap that is used to attach one or more weights to the main body member in a removable manner. Two pairs of upper body pulling straps are attached to the front portion of the main body member, and in a preferred embodiment, the upper body pulling straps include a pair of handles on a distal end thereof. The weight sled may be folded or rolled up for purposes of storage and/ or transport.

A treadmill includes a deck, a first pulley disposed in a first portion of the deck, a second pulley disposed in a second portion of the deck, a tread belt surrounding the first pulley and the second pulley, and a platform incorporated into the deck.

A weighted-squat exercise machine comprises a pivotable, length-adjustable lever, a weight supported by said lever, a support base, and a hip-belt that connects a user to the machine. Weights are supported by the machine at a safe distance from a user. The weighted-lever has an angle with respect to the horizon with a range of from about 35 degrees to about 45 degrees. When a user wearing the hip-belt connects it to the weighted-lever, the weight's gravitational force is transferred to the user providing for the user to perform weighted squats in a safe manner as the weights are spaced from the user. Thus, athletes can safety exercise without a spotter even if using 1000 pound weights. The belt supports the weight about the athlete's hip structure so that there is no stress on the user's neck and spine and no restriction in breathing.

A weight object configured to be lifted from a ground surface includes a first portion made of high-durometer material, a second portion made of elastomeric material having equal to or durometer than the first portion, and a handle for holding the weight object and lifting the object from the ground surface, where the second portion includes spaced holes within the elastomeric material for absorbing noise generated when the weight object is dropped on the ground surface. Alternatively, a weight object which is configured to be lifted from a ground surface, including at least one layer of elastomeric material having spaced holes therein for absorbing noise generated when the weight object is dropped on the ground surface, and an opening configured to receive a handle.

A weight training apparatus, includes a central body comprising a width and a depth, wherein the width of the central body is greater than the depth. The weight training apparatus further includes a first handle comprising an opening coupled to the central body at a first position and a second position on a top surface of the central body, wherein the first handle is positioned laterally relative to the width of the central body, a second handle coupled to the central body at a third position on a first side surface of the central body, and a third handle coupled to the central body at a fourth position on a second side surface of the central body, wherein the second side surface is adjacent to the first side surface.

A weight plate that is comprised of multiple parts that connect to each other around the handle of a progressive resistive device.

Systems and methods for management and scheduling of differential air pressure (DAP) and other unweighted or assisted treatment systems are provided. The methods and systems can include generation of a suggested workout based on matching user data to data of other users sharing similar characteristics using an aggregate database of user information and related workout information. The methods and systems can include matching a user to an available and/or appropriate DAP system. Also provided are methods and systems including performing a workout and uploading performance information to an aggregate database of user information.

Systems and methods for evaluating the performance of an athlete using a strain gauge is described. In some embodiments, the measurement system comprises a strain gauge and a central processing device. The strain gauge can include a power source, an inertial measurement unit (“IMU”) comprising a load cell, a microcontroller, and a wireless communication module. The strain gauge can be configured to output strain data at a rate of at least 1kHz and the central processing device can be configured to receive the strain data transmitted from the wireless communication module.

There is accordingly provided an exercise apparatus including an inner housing upon which a user may stand. The apparatus includes an outer housing rotatably coupled to the inner housing. The apparatus includes a handlebar coupled to and extending upwards from the outer housing. The apparatus includes a mount for retaining one or more weights thereon. The mount operatively connects to the outer housing and is enclosed within one of the housings.

A weight system can be used with exercise equipment to perform workout routines. The weight system can include dumbbell head covers configured to be removably coupled to the heads of the dumbbell. The head covers can be installed on different sets of dumbbells in a workout routine to provide a customized workout. The head covers can have self-cinching end portions and a tubular central portion for extending over the head of the dumbbell. The self-cinching end portions can cooperate to hold the dumbbell head while performing lifts.
