| 20090088304 | EXERCISE DEVICE - An exercise device includes a cylindrical housing closed at one end and having a spring arranged therein. A plunger is connected with the housing and abuts against the spring. The plunger is adapted to reciprocate within the housing against the force of the spring. More particularly, the plunger includes a handle exterior of the housing which is grasped by the user. The closed end of the housing includes a pad which is placed against the chest of the user. The user grips the handle and displaces the plunger against the force of the spring to exercise the biceps muscle. | 04-02-2009 |
| 20100029450 | Crunch ball rotator tension bar exerciser - rotating and tension bar exerciser in which it's movements are controlled by a 360 degree rotating bearing section which connects rotating balls and spindles to each handle of the bar. Using the rotation of the exerciser will causes the body to rotate in ways which otherwise could not be obtained. | 02-04-2010 |
| 20120094812 | EXERCISE BAR HAVING SLIDING HAND GRIPS - An exercise apparatus includes an elongate bar having a medial portion and opposed ends disposed outwardly of the medial portion with a pair of hand grips mounted on the bar in spaced-apart relation and configured to slide along the length of the bar against a resistance force from a first exercise position to a second exercise position. A resistance member fixed to the bar and movably attached to at least one of the hand grips increases the resistance force as the hand grip slides along the bar from the first exercise position to the second exercise position. The resistance member includes inner and outer band attachment mounts spaced-apart along the length of the bar and an elastic band attached to and disposed between the band attachment mounts. A user performs push-up exercises from a prone position and barbell exercises from a supine position or a standing position. | 04-19-2012 |
| 20130005542 | MULTIPLE FUNCTION EXERCISER - An exerciser includes a leg positioning member which is slidably mounted to a slide rod and a damping device is located between the leg positioning member and the slide rod. Two handles are connected to the top of the slide rod. The user sits in a chair and the two thighs clamps the leg positioning member, the hands hold the handles to lift the slide rod to resist the damping device. The handles can also be adjusted to be operated by pivoting them. The handles can be installed to the lower end of the slide rod and the exerciser is arranged in up-side-down, the user can pushes the handles downward. | 01-03-2013 |
| 20130072360 | BACK-EXTENSION CHAIR FOR THE PREVENTION OF LOW BACK PAIN SYMPTOMS - A chair-like exercising apparatus comprises a back, a seat, front legs, rear legs, and resistance element(s) which provide a broad range of resistance force adjustable by the user for the back extension exercise. The chair back pivotally connects to the rear legs directly, and pivotally connects to the front legs or rear legs through the resistance element(s). The resistance element comprises a compress-coil-spring cylinders (or constant-force-spring devices) and the cylinder holders (or the device holders). The resistance level of the back extension exercise is adjusted by switching the interchangeable compress-coil-spring cylinders (or constant-force-spring devices) of appropriate loads inside the cylinder holders (or device holders). A user sits on the chair and sway backward to perform back extension exercise after selecting an appropriate resistance level based on his/her physical condition. The apparatus is simple, affordable and can be used as a regular chair in its locked position. A regular back extension exercise with proper resistance force strengthens the low back muscles (erector spinae), improves and prevents the low back pain symptoms. | 03-21-2013 |
| 20140141948 | PILATES REFORMER - Some embodiments are directed to an exercise apparatus having a frame comprising a first end, a second end and two generally horizontal frame members extending from the first end to the second end, a carriage supported by the horizontal frame members, the carriage being configured to translate along at least a portion of a length of the horizontal frame members and having a planar support surface, a first set of springs supported by the carriage, the first set of springs being configured to extend toward at least the first end of the frame, and a convertible platform positioned adjacent to at least one of the first and second ends of the frame. A vertical height of the convertible platform is adjustable from a first, platform or carriate height position to at least a second, chair position relative to a ground surface. | 05-22-2014 |
| 20150126344 | SELF-LOCOMOTION TRAINING SYSTEMS AND METHODS - Embodiments allow the application of a settable and/or a programmable resistance to a trainee's leg Drive Phase and/or Recovery Phase while walking or running over extended or infinite distances. Multiple mechanical or electrical feedback loops or combinations of both to monitor the applied resistance to the Trainee by the tether or tethers and then control the amount of breaking (drag) or propulsion created by the Mobile training module during the acceleration and constant speed training phases to accurately generate, control and transfer resistance through the elastic tethers to the Trainee. Embodiments apply multiple, non-varying loads or programmable loads to multiple body parts of a trainee where applied resistance can be manipulated to both increase or decrease over distance as desired by trainee while the trainee is walking, running or sprinting over any distance. | 05-07-2015 |
| 20150321043 | COMPACT PORTABLE LEG EXERCISE MACHINE - A compact portable leg exercise apparatus includes a top platform, a base member, a resilient member and a frame assembly interposed between the top platform and base member. The apparatus is sized to receive a foot onto the top platform to move the top platform relative to the base member and against a force provided by the resilient member as the apparatus is moved to the collapsed position. The apparatus is sized to fit in carryon luggage, handbag, backpack or be hand-carried, allowing for its use anywhere. The frame assembly aligns the top platform and base member and inhibits twisting motion of the top platform relative to the base member, thereby constraining the motion of travel for the apparatus. The frame assembly can include a plurality of hinged leaf pairs shaped to inhibit generation of noise by the frame assembly as it moves to the collapsed configuration during use of the exercise apparatus. The exercise apparatus is light weight, small, quiet and stable, allowing for it use at home, the office, in public, in the airplane, or even within a vehicle. | 11-12-2015 |
| 20150352397 | Exercise Device and Method of Use - An exercise device that utilizes a compression resistant means placed between two similarly sized exercise plates that can be hand held and compressed in a variety of exercises. The invention includes methods of exercising in which the exercise device is compressed and utilized in various ways. | 12-10-2015 |
| 20150375031 | Exercise tube with adjustable resistance - An Exercise tube with adjustable resistance can provide different compression resistance strength for exercise. A user can select the correct spring loaded small tubes of different resistance strength to add up to desired total resistance strength and insert them into bigger outer tube and big inner tube. The user can adjust the resistance strength needed for a particular exercise. In addition, different user can share the same exercise tube by adjusting the resistance strength to suit their individual needs. | 12-31-2015 |
