Martin Chuck introduces Smart Ball Sleeve – accessory expands swing drills from arms to hips and legs

A small ball tucked between the arm and the chest is a familiar drill for amateur golfers. But when that ball can be attached to a leg, hip or arm through a new accessory, the story begins to change. Martin Chuck, a GOLF Top 100 Teacher, is the creator of the Smart Ball — a simple training aid that helps golfers keep the arms connected to the body while rotating. According to the product story on GOLF.com, the Smart Ball has been around since 2026 and is still seen on practice tees at most PGA Tour stops. The new addition is the Smart Ball Sleeve, which allows the ball to be attached in more positions and extends training to the lower body. The Sleeve works in a direct way. In the original version, the ball is held against the chest or under the arm to give instant feedback whenever the arms leave the body. Placed higher up the thigh or hip, the drill forces the body to stabilise the pivot and control the lower-half movement. That is a logical technical extension, because an arms-disconnected fault is often paired with poor hip control. What makes this look more like a marketing note, however, is the silence of data. The article claims the product solves a common swing issue but gives no measured numbers: no before-and-after data, no accuracy or distance improvement. The popularity phrasing is also vague — still likely to be found on PGA Tour practice tees — without naming a single professional. If the product is truly widely used, naming users is a simpler and far more convincing piece of evidence. The commercial intention behind the Sleeve is easy to read. Tour Striker, Martin Chuck's golf-tool brand, is following a familiar strategy: extending a proven product with an add-on instead of inventing something completely new. The $57 bundling price also suggests the target is the amateur market, not the premium tier. Technically, moving the training zone from the arms down to the hips is a meaningful signal. It points to a possible shift from a single tool to a whole-body drill system. But before amateur golfers spend $57, the biggest question remains: where are the numbers from real users? Until independent data appears, the Smart Ball Sleeve is just a clever accessory sitting in the grey zone between sports product and marketing promise.
