U.S. Kids Golf RS57 Junior Swing Speed Trainer, 57" (145 cm)
U.S. Kids Golf RS57 Junior Swing Speed Trainer, 57" (145 cm)
The U.S. Kids Golf RS57 Swing Speed Trainer is a purpose-built junior training aid designed to help young golfers develop a faster, more efficient swing — one that mirrors the rhythm and tempo of Tour-level players. By allowing juniors to swing faster than they would with a standard-weight clubhead, this trainer accelerates the natural development of swing mechanics while simultaneously building the specific muscle groups needed for powerful, consistent ball-striking. Just five minutes of daily practice with the RS57 can produce long-term increases in clubhead speed, translating directly into longer, straighter drives on the course.

Technology in Detail
Swing Speed Development
The RS57 is engineered specifically to allow junior golfers to swing faster than they could with a conventionally weighted driver head. By reducing the resistance at the head, the trainer conditions the body to generate higher swing speeds naturally, reinforcing the fast-twitch muscle memory that translates into greater distance when the player returns to a standard club. Over time, this overspeed training stimulus results in measurable, lasting gains in clubhead velocity.
Tour-Level Rhythm and Tempo
Developing a consistent, repeatable swing tempo is one of the most important fundamentals in junior golf. The RS57 Swing Speed Trainer encourages young players to find and maintain the smooth, rhythmic sequencing seen in professional Tour players. By practicing with the trainer regularly, juniors build an ingrained sense of timing that carries over directly to every club in their bag, improving consistency and shot quality across all conditions.
UL57 Driver-Matched Shaft Length
The shaft length of the RS57 Swing Speed Trainer is identical to that of the U.S. Kids Golf UL57 series driver, which is sized for juniors of approximately 145 cm in height. This design choice is intentional: when a young golfer transitions from the training aid back to their actual driver, the feel, length, and swing arc are immediately familiar. There is no adjustment period, meaning every training session directly reinforces the mechanics used during real rounds of golf.
Right- and Left-Handed Compatible
Unlike many training aids that are produced exclusively for right-handed players, the U.S. Kids Golf RS57 Swing Speed Trainer is fully suitable for both right-handed and left-handed junior golfers. Parents and coaches do not need to purchase a separate product for a left-handed child — the same trainer works equally well for both orientations, making it a versatile and cost-effective addition to any junior training programme.
