A muscular training apparatus to present muscular training accessories. The muscular training apparatus has a bottom part including a central panel and two lateral panels on each side of the central panel. The two lateral panels are installed free to pivot about the central panel. The apparatus can be converted between at least one working position and one storage position. In a working position, the lateral panels are unfolded at the sides of the central panel to form a self-supporting structure. In the storage position, the lateral panels are folded adjacent to the central panel. The bottom part further includes a locking element to secure the self-supporting structure in the working position of the apparatus.

An exercise machine for performing prone leg curl exercises, including a moving support platform or frame that allows a user to perform prone leg curl exercises without excessively arching his or her lower back.

An exerciser including a movable body carriage mounted on an exerciser frame for movement along tracks provided by the frame. A resilient foot engaging assembly extends from the exerciser frame. The resilient foot engaging assembly is adapted to be engaged by the user's feet to absorb the energy of movement in a first direction and to provide the user with a bouncing movement, which the user may translate into a movement of the movable body carriage in the opposite direction. The resilient foot engaging assembly may be provided as an attachment and retrofitted to existing exercisers. The resilient foot engaging assembly includes a unit mounting frame assembly and an independent usable exercising unit, such as an inflated dome or trampoline unit, removably secured thereon. The exerciser may include a resilient resistance system coupled to the movable body carriage and a set of pull lines with user grips trained over pulleys carried by the exerciser frame. Also disclosed are methods for enabling users to exercise in either one of two different modes.

The invention is an exercise apparatus providing an advanced level of surfboard paddling simulation and muscle development. The design includes a specialized platform, unique hand harnesses, and cable systems with mechanical advantage and mass moment of inertia mechanisms, piston pumps, cable spools, and elastic elements. They allow the user to simulate paddling in an alternating or simultaneous sequence at any speed while strong elastic tension resists the user's thrust strokes, but during paddling return strokes the user feels no elastic tension or resistance. The design also prompts the user to engage and strengthen all dorsal muscles to maintain an appropriately arched body position while paddling.

Elevating rims allow the central hub of a back roller to be elevated from the ground. Elevating the back roller allows the user to increase their flexibility as they bend their back over the central roller. A user can purchase one or a set of rims to interchange the back roller and rims to accommodate different stretching and exercises. The joining mechanism can be threaded coupling in one or both of the hubs or can be a telescoping connection with or without a spring-loaded pin in a hole. The rims can have ribs to allow an installer to grip the rim and twist the rim on an axle. The back roller can be fabricated with an internal thread where changeable rims can be threaded into the inner diameter of the back roller to change the amount of elevation.

An exercise device has a base with a plurality of rollers secured to a bottom surface thereof. A handle with an extended stem is rotatably attached to two columns that extend from a top surface of the base. A brace is attached to the stem and designed to comfortably contain the forearm of a user. The handle is connected to a spring that applies a rotational bias when the stem is rotated away from a starting position. In operation, an individual assumes an initial push up stance and grasps the handles of two such devices, with the brace positioned underneath each forearm. As the user stretches outward, the base rolls along the brace and pushes up against the forearms. This assists a user when retracting to the initial stance.

A device for multidimensional mobilization of lumbar, pelvic, and hip joints with a generally concave upper surface connected to a generally convex lower surface is disclosed, wherein the generally concave upper surface has a recess to cradle a sacrum.

A device for exercising the gluteal muscles. The device is simple, small, portable, and lightweight, comprised of a half roll with a handle in each end. The user, facing down on top of the device at the level of the hip bones, must keep the legs high in a cantilever position which will exercise the gluteal muscles. To keep the legs in cantilever, the hamstrings muscles, lower back muscles, arm muscles, and core muscles are also exercised; the latter muscles are especially exercised if the upper body does not rest on a surface and is used for balance.

An exercise machine for performing prone leg curl exercises, including a moving support platform or frame that allows a user to perform prone leg curl exercises without excessively arching his or her lower back.

An exercise device for use by a user on a support surface comprises a support assembly, an extendable neck, and one or more resilient first resistance assemblies. The support assembly supports the user relative to the support surface. The support assembly includes a support body that is engaged by the user, and a support base that supports the support body, the support base resting on the support surface. The extendable neck is movably coupled to the support assembly. More particularly, the extendable neck is selectively movable relative to the support assembly between a retracted position and an extended position. The one or more resilient first resistance assemblies are secured to the extendable neck.
