An exercise device that simultaneously incorporates both balance and resistance training comprises a base including a rear and a front portion; a balancer disposed in the base proximal to the front portion of the base and configured to both support a user thereon and move with weight shifting by the user thereon; one or more lines retractably disposed in the front portion of the base; a resistance mechanism disposed in the base and operably associated with the one or more lines, wherein both balance and resistance training are provided by the balancer and the resistance mechanism when a user attempts to balance the user's weight on the balancer while pulling on the one or more lines.

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.

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.

A support shirt comprising a shirt body and a pair of shirt body sleeves positioned adjacent to an upper shirt body is provided. The sleeves are attached to the shirt body at sleeve body holes, with each of the sleeves including sleeve reinforcement regions extending at least a portion of the distance from the sleeve holes to an outer edge of the sleeves. The sleeve reinforcement regions extend substantially along a centerline extending longitudinally across the sleeves and the upper sleeve body to stabilize and provide support to the shoulders of a wearer during an upward lifting motion.

A rowing machine convertible for use both indoors and outdoors. In the outdoor mode, the rowing machine is configured for adaptation to a watercraft, such as a kayak or stand up paddle board (SUP). A rower operating the rowing machine pulls on a rope or cord to cause paddles positioned at the rearward end of the machine to rotate and move the machine on a body of water. In the indoor mode, legs are attached to the machine for placement on a rigid surface. The paddles are placed in a container holding fluid.

A hybrid paddle for use in both a standing and a kneeling position is disclosed. The paddle has a shaft terminating in a blade at each end. At or near each throat or junction between the shaft and a blade is a handle. The handle has a grip sufficiently offset from the blade to allow a user to grip the handle without his or her hand colliding with the blade. While kneeling, the user grips the shaft with both hands, and alternates the placement of the blades in the water. While standing, the user grasps the handle with one hand and the shaft with the other hand, and a single blade is placed in the water. In this way, the same paddle is used in both the standing and kneeling positions, and the user can alternate between standing and kneeling as desired.

A support shirt comprising a shirt body and a pair of shirt body sleeves positioned adjacent to an upper shirt body is provided. The sleeves are attached to the shirt body at sleeve body holes, with each of the sleeves including sleeve reinforcement regions extending at least a portion of the distance from the sleeve holes to an outer edge of the sleeves. The sleeve reinforcement regions extend substantially along a centerline extending longitudinally across the sleeves and the upper sleeve body to stabilize and provide support to the shoulders of a wearer during an upward lifting motion.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

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.

The present invention relates to systems and devices for improving of a rower's technique. In particular, the invention provides one or more clamps that can be used in conjunction with a rowing machine to provide external cues that the rower can use to monitor and correct his or her catch technique without the assistance of a coach or other person.
