Apparatuses, systems, and methods of use are disclosed for enhancing upper body exercise. An apparatus includes a domed hand support section, the domed hand support section having a plurality of recesses configured to receive a palm, thumb, and fingers of a user's hand while the user's hand is held in a naturally curved open-position. The apparatus also includes a surface engagement section secured to an underside of the domed hand support section and configured to engage a supporting surface. When the surface engagement section is deployed on the supporting surface and the palm, thumb, and fingers of the user's hand are placed in the plurality recesses on the domed hand support section, the domed face supports the user's hand in the naturally curved open position while the user exerts force against the domed hand support section and that is at least partially directed toward the supporting surface.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

Disclosed are systems and methods for plyometric fitness systems that facilitate constrained multi-directional movements. By utilizing a variety of constrained elastic resistance cords in conjunction with plyometric platform stations and performance patterns, this system enhances dimension, capability and variety to conventional agility and jumping drills. The disclosed plyometric platforms are designed for contrast training, or resistance loaded and unloaded exercises. This allows the muscles to adapt to the loaded exercises and then apply the “learned” movement to the unloaded exercise. This directly reinforces the movement and muscle exertion needed to perform powerful movements thereby enhancing athletic performance.

In embodiments of animation using keyframing and projected dynamics simulation, an animation object is displayed with handles associated with object regions for the animation object, each handle being selectable for setting animation constraints on an object region. An animation simulator receives a user input designating a particular handle with an animation constraint, and sets the animation constraint on the particular handle for the associated object region. The animation simulator also receives another user input, designating a timing of the object region associated with the particular handle of the animation object through multiple frames in an animation sequence. The animation simulator projects a simulation of the animation object utilizing a projected dynamics algorithm that applies physics to simulate the set of object regions of the animation object in the animation sequence, the simulation including simulating the object region associated with the particular handle based on the timing and the animation constraint.

An exercise apparatus or machine according to the present disclosure is adapted to support a user above a floor while the user performs hip thrust or other exercises. The exercise machine includes a head support and a foot support for supporting the torso and feet of a user so that the hips of the user are suspended in an exercise area between the head support and foot support.

A hand strength appliance is provided that may be used in multiple or selected configurations for grip and pinch strength assessment as well as grip and pinch exercises. The appliance includes a frame and a sliding internal handle fitted within and slidable within the frame, and may be positioned for multiple test positions and exercises. The appliance may include and be used with a force sensing device that may transmit information to a computing device.

A sports wrist trainer comprising a first elongated swing member with grip attached to a second elongated swing member with head by means of a one way 90 degree hinge, and an elastic return means that returns and holds said swing members at a ninety degree angle one to the other. According to alternative embodiments, the wrist trainer is a bat used for learning batting swings or a golf club used for learning golf swings. The one way hinge rotates to provide a trainer having different swing configurations and to maintain the bat or club head facing the ball at impact just like at address. The elastic return means may be removed and the trainer used without it. A second one way 90 degree rotating hinge can be added to the first providing additional versatility and accommodating both right and left handed golfers.

A posture and movement training garment 100 comprises at least one elastic element 1-22 arranged to be stretched upon movement of the wearer's trunk and/or at least one of the wearer's limbs away from a predetermined rest or neutral position, thereby to provide the wearer with gentle elastic recoil sufficient to provide the wearer with additional kinaesthetic and/or touch feedback resulting from the movement, substantially without inhibiting the movement. A complementary sports training or physiotherapy garment 300 comprises a fabric base and pockets 50-55 for the reception of weights, the garment further comprising strips of relatively inextensible material 67 forming a network interconnecting the base material within the pockets, in which the majority of the strips run generally longitudinally of the wearer's limbs and torso and form a branched network with bases mainly originating at the wearer's shoulders and/or hips; and wherein the network does not completely encircle the wearer's limbs and torso. The weights may comprise a body 220 formed from an elastomer, in which the body contains an embedded plurality of pieces 216 of a harder, denser material, each piece having a minimum dimension of at least 1.5 mm and in which the individual pieces are movable relative to one another, whereby the body retains its flexibility.

A fitness structure includes a bar having a first end portion and a second end portion, a pair of bar support portions provided at each side of the bar and having a plurality of bar support members to place the bar at a plurality of heights, a first load portion and a second load portion spaced apart from the bar to a certain degree and facing each other, a first cable coupled between the first end portion of the bar and the first load portion, a second cable coupled between the second end portion of the bar and the second load portion. Heights of the first load portion and the second load portion vary depending on a height of one of the plurality of bar support members at which the bar is detachably placed.
