Abstract: There is provided an article of adjustable drag resistance water exercise equipment comprised of a rectangular piece of material (11) with a handle (12A) attached to either end, and an identical handle (12B) looped around the material. By holding the handles (12A-12B) in either one hand or both hands of a user, or one handle (12A or 12B) placed around one foot while the user holds the other handle(-s), it can be moved through water in multiple directions through several movement planes, therefore increasing muscular strength and endurance of upper and lower extremities and core muscles of the user, as well as improving stability and balance. The device can be adjusted for user length and resistance levels using the third handle (12B). The equipment is useful in aquatic therapy or group exercise situations with different populations (elderly, injured, overweight, the elite athletes, recreational fitness partaker, and many more) to increase surface area and drag.

Abstract: A multi-purpose fitness bar capable of being asymmetrically weighted. The fitness bar has a frame consisting of three arms, multiple handholds and elevated risers. The handholds are in a multitude of positions and angles to provide variability in training. Each arm is capable of being independently loaded with one or more removable weights to produce a symmetric or asymmetric weight load to provide increased torque with movement of the device as well as driving the body in movement patterns consistent with function. The elevated risers provide a space between the body of the device and floor to provide “push-up” function of the device by protecting the users hands from contact with the ground. The arms of the device may also provide attachments for resistance band use to provide another loading mechanism for strength development.

Abstract: A spacer that is preferably made from high density polyethylene and has a diameter that is larger than a standard plate for a barbell. The spacer has a central hole dimensioned to accept a standard barbell and, when placed onto a barbell, will space the barbell apart from the ground a sufficient distance that a user can easily add or more plates from the barbell without having the lift the barbell. The spacer provides a more efficient way to add or remove weights from a barbell that is on the ground (e.g., when a user is performing deadlifts, snatches, and power cleans, etc.). The spacer may be placed on a barbell similarly to a regular weight plate, preferably before any other weight is added.

Abstract: A barbell collar system which is both easy to connect or disconnect from the barbell and secure enough to maintain weights on a barbell during extreme use. The barbell collar system generally includes a collar which is adapted to easily and quickly be connected to or removed from a barbell to retain a weight on the barbell. The collar is adapted to adjust between a first position in which the collar is curled around the barbell outside of the weight and a second position in which the collar is elongated in a linear orientation. The collar may include a ribbon spring for snapping between the two positions and an outer covering for increasing friction between the collar and the barbell. One or more magnets may be included with the collar to magnetically engage the collar with the barbell or the collar with itself.

Abstract: A cordless treadmill including a frame, a belt system, and a drop-in cartridge is disclosed. The cartridge includes a plurality of staggered rollers configured to provide tactile feedback to the user. The frame is adapted to receive the belt system and the cartridge as they are lowered into the frame, and the frame is adapted to place the belt of the belt system into tension as the belt system is lowered into the frame. An integrated flywheel generator system provides smooth operation of the treadmill and generates electricity to power additional systems.

Abstract: In one aspect of the present exercise machine, an assembly is attached to the end of a reformer, where the assembly comprises a seat mechanism and a pedal mechanism. The seat mechanism has a seat, a bracket supporting the seat, and a height adjustment system, where activation of the height adjustment system permits selective adjustment and locking of the height of the seat and the bracket by restricting travel of the seat and bracket to a slanted path that is slanted relative to the vertical. The pedal mechanism has an axle, a first pedal arm with a first pedal, and a second pedal arm with a second pedal. The pedal mechanism is located directly beneath the seat when the seat mechanism is in a lowest position and partially exposed in a higher position.
