Described herein is a modular skate system that includes at least one modular skate component comprising a major surface, a core comprising a body formed from a first material, an outer layer formed from a second material, the outer layer surrounding at least a portion of the core, wherein the first material is different from the second material, and wherein the major surface comprises the outer layer.

Embodiments of the present invention provide a method and apparatus for providing training to a surfer. The method involves highlighting the critical elements of the surfing region, enabling a surfer to comprehend complex dynamic environments, (such as barrells), better understand what expert surfers do in such environments, and then progressing such maneuvers from the mind to the physical environment as actual performance. The apparatus comprises a sensory cue generator capable of delivering cues that enable a surfer to visualize maneuvers in their mind, practice in virtual/augmented reality, and the physical environment in artificially and naturally generated surfing conditions. The sensory cues are delivered dynamically to the surfer, in an intuitive fashion correlated with the surfing visualizations, simulations or environments, prompting the surfer to deploy correct surfing maneuvers, greatly reducing the learning curve and progressing physical and mental performance as never before.

Described is a sand training bag for sand training. It includes a set of bag walls which includes a training surface wall and a perimeter wall. The sand training bag is transitionable between a closed bag configuration in which the set of bag walls defines a bag chamber to an open pit configuration in which the set of bag walls forms a sand training pit with the training surface wall forming a floor of the sand training pit and the perimeter wall forming a perimeter side wall of the sand training pit, the sand training pit being provided to receive and hold a quantity of sand.

A board paddling training apparatus for assisting in improving a user's paddling technique and strength. In particular, the board paddling training apparatus includes a buoyant board, such as a board adapted for surfing, bodyboarding, paddleboarding, or other board-related sport that entails paddling, and includes a resistance mechanism that creates drag or resistance against a user's paddle stroke. Some implementations of the resistance mechanism can be adjustable in order to create a variety of resistance against the user's paddle stroke and board movement.

A resistance trainer that provides for rotational movement, balance training and strength building. The device is an integral one-piece fabricated from wood or plastic that includes a deck that is detachable from the base. The base in includes two separate dome-shaped reservoirs wherein the domes provide instability when in contact with the ground due to the curved surface. Inside of the domed reservoirs is space to add a weighted component, such as standard plate weights or sand or water or other replaceable means of weighting the device. The user can rotate the board using the torso muscles used when surfing or snowboarding and can also balance in a heel to toe direction or a front to back direction for balance and strength building.

An exercise apparatus comprises a body having a top surface adapted to support a user standing thereon, an endless band extending around said body along a path substantially perpendicular to said top surface, said endless band being slidably supported by said top body for rotational movement thereabout and a plurality of protrusions extending from said endless band adapted to be engaged upon by an object manipulated by the user.

Method of using a snowboard training apparatus for transferring the feel of toe side and heel side of a snowboard from an instructor to a snowboard learner is disclosed. The training apparatus includes a training rod having a first and second end. The first end and second end of the training rod can be adapted to be supported by a snowboarder's leg, snowboarder's boot, snowboard's bindings or a snowboard itself. The training apparatus can also include a second training rod.

A wave making apparatus for creating a surfing wave in a body of water. The waves are generated using a controlled up and down motion of Fiber Glass, (FRP), or EPS Geo Foam Mechanical Plungers in a way that allows the control and shape and therefore surf characteristics of the wave. The plunger wave making apparatus is assembled side by side in a vertically manner on a 45-degree sloped back wall. Water ballast is added to the front and main compartments of the wave making plungers to optimize power requirements to power the plungers up and down to produce the waves into the body of water.

A wave generating system.

Disclosed embodiments may include a trampoline scooter device for practicing scooter tricks on a trampoline. The device may include a foam deck with an upper surface and lower surface, where the upper and lower surface both contain a recess. The recesses are designed to receive, respectively, an upper attachment member and a lower attachment member. The upper and lower attachment members and the recesses contain aligned holes to receive connectors. The connectors, or bolts, extend through both attachment members and the deck to secure the deck to the attachment members using nuts. The upper attachment member is connected to the headtube of the scooter via the neck. The headtube contains connections to the column. The column is attached to handlebars containing grips and grip ends.
