A fully portable exercise system and apparatus utilized for exercising, stretching, and training multiple muscle groups of the body of a user. The apparatus has at least one closeable pocket and fixation rings for securing and carrying accessories, such as attachable handgrips, adjustable suspension straps or lines, and elastic bands. Another configuration illustrates a suspension training system comprising non-elastic suspension sub-assemblies, elastic suspension sub-assemblies and handgrips, configurable with or without the portable exercise apparatus. The apparatus and methods of use provide the user with a plurality of configurations for assisted exercise regimens and the flexibility to exercise anywhere. The apparatus is adaptable to be worn about the waist of a user, carried as a bandolier about the user's body or utilized as a releasably fixed suspension trainer.

A cover assembly may include a housing and an elongated cover. The housing defines a chamber therein. The chamber is disposable in the ground adjacent to a side of the sand area of the jump pit. The elongated cover has a first end, a second end, and spaced-apart sides extending from the first end to the second end. The elongated cover is storable in a compacted configuration in the chamber of the housing below the surface of the ground, and the elongated cover is removable from the chamber and extendable in an uncompacted configuration over the sand area of the jump pit to conceal the sand area.

A training aid stimulator for providing fast perceptive feedback, the training aid stimulator comprising a first skin electrode for making electrical contact to the body of a user, and a second skin electrode for making electrical contact to the body of a user, a body capacitance charging module connected to the first skin electrode, a discharge module connected to the second skin electrode for a feedback discharging of a body capacitance, and a processor connected to the body capacitance charging module for controlling the charging of a body capacitance, C.sub.BODY, to a predetermined first voltage level, wherein the processor further being connected to the discharge module for controlling a feedback discharge of said body capacitance, C.sub.BODY, and wherein the stimulator further comprises a measurement module for measuring the level of charge of said body capacitance, C.sub.BODY.

A portable exercise apparatus utilized for exercising, stretching, and training multiple muscle groups of the body of a user. The apparatus is adapted to be worn about the waist or carried as a bandolier about the user's body. The apparatus has at least one releasably closable pocket and fixation rings for securing and carrying accessories, such as attachable handles, suspension lines, and elastic bands. The apparatus and methods of use provide the user with a plurality of configurations for assisted exercise regimens and the flexibility to exercise anywhere.

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.

A device for marking a starting point on a running track. A plurality of spikes is affixed to a bottom surface of a planar member. A top surface of the planar member can receive print thereon. The plurality of spikes can be inserted into a running track. A plurality of conical covers houses the plurality of spikes when the plurality of spikes is not inserted into a running track. The planar member can be rectangular with a spike disposed in each corner on the bottom surface.
