An indoor exercise bicycle having a magnetic brake. The magnetic brake system has a pair of parallel arms each having a set of magnets. The pair of parallel arms moves along a track in a radial direction relative to the axis of the flywheel. The pair of parallel arms move toward and away from the flywheel not via a pivoting action. Instead, the pair of parallel arms moves linearly towards and away from the flywheel.

An interchangeable and weight adjustable golf grip including at least an end cap body having integral receiving ports adapted to receive variable weights, electronic chips, sensors, gauges, lasers, cameras, or biometrics within and wherein the end cap is capable of housing the various weights, chips, sensors, etc. within the end cap so that a player can interchange the weights or sensors without removing the golf grip from the shaft in order to make adjustments and so that the player can play golf without removing any other portions of the grip. Further, the invention includes contemplation of a tip collette with integral receiving ports adapted to also harbor similar weights, or sensors, etc. Data from the sensors may be transmitted by Bluetooth transmission to a smartphone or a ball launch monitor system for analysis.

Accessory systems configured to convert motion from a given exercise device into computer readable instructions for a given general-purpose computer. The accessory systems include a microcontroller and a sensor. The microcontroller is in data communication with the given general-purpose computer. The sensor is in data communication with the microcontroller and mounted in a position to monitor the given exercise device. The sensor is configured to detect motion of the given exercise device and to send motion data to the microcontroller. The microcontroller is programed with computer executable instructions to convert the motion data into computer readable instructions for the given general-purpose computer. In some examples, the accessory system includes a magnet, a first supplementary input, a second supplementary input, and/or a user input device.

Customizable golf putters are disclosed. The putters include a putter face; a putter head that is configured to be reversibly connected to the putter face (with the putter head being selected from a plurality of different putter head styles); and a hosel that is configured to be reversibly connected to any of a plurality of hosel receiving channels that are accessible on a top surface of the putter head (the hosel is also selected from a plurality of different hosel styles). The golf putters further include a threaded shaft connector that is configured to reversibly connect the hosel to a putter shaft. In addition, the golf putters include one or more peg fillers, which are configured to be inserted into empty hosel receiving channels.

An indoor, stationary, bicycle training device that provides advantages over conventional designs of exercise bicycles is provided. The stationary bicycle may include a tilting/pivoting mechanism to orient the indoor bicycle to simulate descending or climbing. The indoor bicycle may include flexible and resilient frame elements to support the indoor training device to move side-to-side under some riding situations thereby simulating the side-to-side swaying motion of an outdoor bicycle under the same riding situations. The indoor bicycle may include several combinations of frame adjustments to provide configurable dimensions of the indoor bicycle to adjust the frame to properly fit the rider, which may be adjusted based on corresponding dimensions of a user's outdoor bicycle. Still other aspects of the stationary bicycle device may aid in creating an “outdoor” feeling while using the device.

A golf swing training apparatus has a shaft, a housing with a top cap and a bottom cap, and a plurality of weighted discs receivable within the housing. A golfer may adjust the weight of the head of the club by adding or removing weighted discs in the housing. The golf swing training apparatus may comprise an accelerometer within the housing so as to measure the speed, acceleration, and swing path that the club takes for feedback and analysis to improve the golfer's swing.

Disclosed herein is a modular kettle-bell shaped dumbbell having separate, equally weighted dumbbell portions that may optionally be used separately or may be temporarily joined together to form a single kettle-bell shaped dumbbell of twice the weight of the separate, equally weighted dumbbell portions. Each of the separate dumbbell portions may include one part of a two-piece connection system configured to temporarily lock the separate dumbbell portions to one another, with such connectors being configured such that upon achieving a fully engaged locking connection, the exteriors of each body portion of the first dumbbell portion and the second dumbbell portion together form a generally spherical main body portion and an upwardly extending handle having a generally circular cross-section throughout its length.

The present invention relates generally to the field of hockey nets. More specifically, the present invention relates to an improved hockey mininet and GoalScreen. The mininet is comprised of a mininet structure, a GoalScreen, a puck, a ball, and a simulated ice surface. The GoalScreen can further removably and magnetically attach to the mininet structure via a magnetic frame and is comprised of framed mininet netting that returns a puck or ball to the user once the puck/ball has been shot at the screen. Further, the mininet may be comprised of a removably or fixedly attached simulated ice surface that mimics the feel of real ice. The mininet attaches to the simulated ice surface structure via a magnetic means or other means. The simulated ice surface may be comprised of a plurality of attachable sections to allow for easy transport and storage.

An exercise machine with a slidable carriage and accessories providing for a plurality of exerciser positioning surfaces and gripping handles. The exercise machine generally includes one or more lifting handles for raising or lowering either end of the exercise machine with respect to a ground surface. The exercise machine may also include a plurality of wheels each including a ridge adapted to engage with a corresponding groove in a track of the exercise machine. The exercise machine may also include a handle including a pair of arms which are positioned at a distance just greater than a width of the carriage.

A technical swimming paddle for assisted stroke execution consists of two generally planar elements connected by a longitudinal fold that only admits movement of said elements when pressure is exerted from the side corresponding to the back of the hand, while locking them into aligned co-planar configuration when pressure is exerted from the opposite (palmar) side. The connecting device is specifically designed so that movement of the adjoining elements disrupts the swimmer’s ability to hold and utilize the paddle, therefore discouraging the application of pressure from the direction associated with the back of the hand, and serving as real-time feedback on the potential presence of said pressure during stroke execution. In this manner, the device allows users to fine-tune stroke execution towards optimization of their swimming technique.
