A waterproof apparatus including a waterproof enclosure including electronic circuitry, a solar panel and a keypad. The electronic circuitry is configured to communicate data wirelessly when pressure is applied to the keypad. The waterproof apparatus may be mounted to watersport equipment, such as a surfboard, kiteboard, kayak, wind surfer jet ski, paddle board, or a wakeboard.

A method and system are disclosed using a position sensor for tracking a trajectory of a paddling instrument. Optionally the trajectory may be used for determining a paddling improvement strategy, for recognizing a stroke type, for coordinating a rowing team and/or for calculating a paddling force.

An exercise assembly structured to perform different rowing routines characterized different rowing motions. A resistance device is movable within a chamber and is cooperatively structured therewith to resist such movement. A drive assembly includes two drive sections each independently connected in driving relation to said resistance device. A connector structure includes two connector members each attached to a handle and connected in driving relation to a different one of said drive sections. The handle is selectively movable through the plurality of different rowing motions, at least one of which results in the two drive sections concurrently driving the resistance member and being concurrently driven by the two connector members. At least one other rowing motion of the handle is defined by each drive section alternately driving the resistance member and being alternately driven by interconnected ones of said connector members.

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 combination paddle and fishing rod device is disclosed. The device may incorporate a single ended paddle or double ended paddle. In any embodiment, the device allows a fishing reel to be mounted to the shaft of the paddle. The shaft forms a portion of the fishing rod supporting one or more eyelets for guiding fishing line from a fishing reel mounted to the shaft. In one embodiment, the eyelets are connected to the shaft and or an oar blade. In another embodiment, a short fishing rod section having one or more eyelets is connected to the shaft. The device is configured to permit fishing while a user propels a watercraft.

Methods, apparatus, systems and articles of manufacture for measuring and adjusting physical resistance for athletic activities and fitness equipment are disclosed. An example system includes a user-wearable sensor to measure a first level of physical effort during a first athletic activity using fitness equipment and to generate sensor data indicative of the measured first level of physical effort. The example system also includes a controller to receive the sensor data to perform a comparison of the sensor data and data from second athletic activity indicative of a second level of physical effort, and automatically generate a control signal to adjust a setting of the fitness equipment based on the comparison.

Embodiments of the present disclosure are directed to a portable muscle therapy device that can be used for physical therapy, fitness and exercise by creating compression to a joint/muscle while performing movement exercise (flossing) to restore mobility and pain relief. The muscle therapy device may include an elongated shaft comprised of a plurality of detachable segments that allow a user to change a length of the elongated shaft and convert the elongated shaft into separate bars. For example two bars may be formed, one for each hand of the user, and a resistance band may be attached to each bar. Additionally, the muscle therapy device of the present disclosure provides for an ability to attach a handle on one end of the elongated shaft to mimic a canoeing and stand up paddle for back, core and shoulder exercise.
