The improved how comprises a pressure sensitive adhesive (PSA) tape on the rail or arrow rest, the surface the arrow slides over when released. The PSA tape provides a smooth surface for the arrow to glide over thereby reducing friction. This is an improved over prior art products such as rail lube or silicone products.

Abstract: A swing training device for baseball, softball, golf players, and potentially racquet sports players that provides feedback as to where the ball is hit. The swing training device comprises a first vertical member rigid and columnar in form connecting to a first horizontal member, being rod-like in form, at a first end. A second end of the first horizontal member comprises a ball-shaped end connecting with a swivel joint to a second vertical member. The swivel ball joint connection allows the second vertical member to rotate at an angle such that the player knows whether their hit contacted the ball in the center, or to the left or right of center, thereby allowing the player to make adjustments in their swing based on angle of rotation of the ball around the first horizontal member.
