Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.

Embodiments of golf club heads with turbulators and methods to manufacture golf club heads with turbulators are generally described herein. Other embodiments may be described and claimed.

A high moment of inertia aerodynamic golf club head with a low deep center of gravity location and producing reduced aerodynamic drag forces. The club head has crown section attributes that impart beneficial aerodynamic properties and performance.

An improved exercise equipment including a stationary exercise apparatus, a lever arm pivotably biased about a pivot axis, and a support for supporting the lever arm above the stationary exercise apparatus. The pivot axis extends substantially in a vertical direction. The stationary exercise apparatus is of a type to cause the legs of a user to scissor as the user operates the stationary exercise apparatus. In an exemplary embodiment, the stationary exercise apparatus is a treadmill.

Embodiments of golf club heads having transition profiles to reduce aerodynamic drag during a swing are described herein. In some embodiments, a golf club head includes a crown transition profile having a first crown radius of curvature, a sole transition profile having a first sole radius of curvature, and a rear transition profile having a rear radius of curvature.

Disclosed golf club heads include a body defining an interior cavity, a face, a sole, a crown, a skirt, and a hosel. Some embodiments include one or more of a split mass pad and/or one or more weight ports positioned in a sole portion of the body. Additionally or alternatively, one or more mass pads or weight ports may be positioned adjacent to the periphery of the sole portion. Some embodiments further include an adjustable head-shaft connection assembly configured to adjustably couple the hosel to a golf club shaft.

An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.

A leg muscle, abdominal muscle, and spinal exercise device adapted for imparting curvature to a lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force includes a frame for placement on a floor. The frame has a top surface and a bottom surface, wherein the top surface and bottom surface are in a spaced apart relationship forming a hollow portion there between. At least one inflatable bladder is carried by the top surface of the frame. A body strap attachment passes through the frame in non-fixed relationship and is partially disposed within the hollow portion for encompassing the user's thoracic-sacral spinal region and securing said frame. An elongate stirrup strap member is attachable to the body strap attachment thereby connecting to the user's spinal region. A stirrup is attachable to the stirrup strap member distal end.

Disclosed, among other things, are a golf accessory platform and example golf accessories, offering functionality of holding headcovers, gloves, hats, or other items while on and off of a course, offering protection when clubs are being transported or in play, being used as a training device such as an alignment rod, training for increasing swing speeds, storing alignment rods, sticks, or other golf accessories. It may also allow swing tracking practice, provide a way to protect oneself, and provides a prominent space for advertising or branding opportunities.

The present invention is a toy launcher system. A lightweight projectile has an exterior surface symmetrically disposed about an imaginary longitudinal axis and is generally spool-shaped. The launcher is composed of a shaft to which a flexible curled band is attached. The flexible curled band holds the projectile within its curvature. When the launcher is rotated by a user using a general throwing motion the band uncurls, thereby launching the projectile into flight.
