An abdominal exercise device includes a frame comprising top, middle, and bottom frame sections. The middle frame section has a curved shape for creating a teeter-totter movement during exercise. The device includes a headrest connected to the bottom frame section, a plurality of connectors for connecting elastic bands to the frame, and an elastic band connected to at least two connectors. The two ends of the elastic band are connected to two straps. The device creates the teeter-totter movement to exercise the abdominal muscles in response to a person lying down in supine position with the back of the head on the headrest and the feet in the two straps, the person applying a downward pressure with the feet to the straps to move the headrest from a resting position, and the person removing the downward pressure to allow the headrest to go back to the resting position.

Methods and devices for isolating muscle groups during exercise are provided. According to an aspect of the invention, a device includes a first strap that has a first loop shape, a second strap that has a second closed loop shape defining a fixed opening, and a third strap that has a third closed loop shape. A first portion of the first strap is affixed to or integral with the second strap, a second portion of the first strap is arranged to be movable within the fixed opening defined by the second closed loop shape, the second portion of the first strap is affixed to or integral with the third strap, and a first adjustable opening within the first loop shape is configured to be adjusted by changing a relative position of the second portion of the first strap and the fixed opening defined by the second closed loop shape.

Hand-held, portable exercise device which enables the user to strengthen muscles and joints by performing various exercises, the device having a base structure defining a receptacle and supporting at least three omnidirectional rotational elements. A grip element, which may be spherical, has a lower surface positionable on the receptacle and has an upper gripping surface that is convex in at least two dimensions. A hand retaining strap is positionable over the gripping surface of the grip element such that a hand of a human user, the hand having a palm surface and a back surface, can be inserted between the retaining strap and the gripping surface, the palm surface of the user's hand contacting the gripping surface while the retaining strap contacts the back surface of the user's hand to secure the exercise device to the hand.

An exercise system includes an exercise device and a wearable article. The exercise device includes a frame and a user contact point connected to the frame. The wearable article is configured to be worn on a user's body. The wearable article includes a magnetic connector that, when positioned proximate to the user contact point, applies a magnetic attraction force to the user contact point.

A therapeutic exercise device for improving arm mobility and strength is provided. The device can be used by any person but is particularly helpful for infants who suffer from the disease of arthrogryposis. The device includes a base having a first upright leg member and a second upright leg member. The leg members are height-adjustable. The leg members are joined at their upper ends by an upper crossbar member. Preferably, a pair of elastic straps are coupled to the crossbar. The elastic straps can have handles so the infant can reach up and grasp them. The infant can pull downwardly on handles and move the straps. These exercises help infants to improve their strength, range of motion, and sensorimotor development.

An exercise roller includes an elongated bar having grip handles arranged at opposing axial ends of the elongated bar, a cylindrical core supported by the elongated bar between the grip handles, and a cover that surrounds the cylindrical core and is formed of a material having a repeating pattern.

The invention provides an exercise device used by a person to perform abdominal exercises, where the device comprises a weighted ball designed such that the user U can “single-hand drive” the ball through both the concentric portion and eccentric portion of the exercise movement without experiencing unwanted twisting motion of the ball while it is being held during performance of the abdominal exercises. A tether assembly includes a first tether segment and a second tether segment, both being affixed to an outer surface of the ball by a top connector assembly and a bottom connector assembly to define a first and second gaps. The top and bottom connectors reside along a connector axis that extends through the center of the ball. A first coupler extends from the first tether segment for operable connection to a resistance assembly. A second coupler extends from the second tether segment for operable connection to the resistance assembly. The first and second couplers are in an opposed positional relationship and are oriented 90 degrees from each of the top connector assembly and the bottom connector assembly.

A spring exercise system and method of exercising that allows a user to perform a full body, low-impact style of exercise. The system utilizes a non-fixed extension spring that stretches and generates resistance when pulling and pressing forces are applied. The extension spring or springs are stretchable between multiple types of interchangeable grasp handles which may include any combination of a resilient loop handle with or without double “D” rings, a single rigid handle, and/or a resilient double loop handle. The spring may have a swiveling link or other mechanism/structure that joins the free ends of the spring to the grasp handles allowing a 360° rotation. The grasp handles are used with combinations of hands and feet, arms and legs to generate an extension of resistance that stretches, strengthens and tones muscles, enhances flexibility, core strength, joint stability, and muscle balance.

Embodiments disclosed herein offer protective restraint of the hand by securing it with a wrist tie to a padded transparent hard-shell hand restraint with wrist tie slots, multiple ventilation holes, a detachable flexible soft under wrap and a hinging ball-bearing style attachment point for optional attachment to a restraint arm rod and staff-directed upward displacement for enhanced access to the hand, and slots for a resistance band tie for enhanced exercise and intermediate level of restraint and a rigid tie.

Systems and methods for a small light weight unit that can be securely held and centered in the palm of the holder during physical activities, such as exercises, including aerobic exercises. The weight unit also includes features for securing the weight in the palm during the exercise to achieve a specific desired weight and intensity of workout.
