PostureLock Swing Trainer for Arm Distance & Structure

When your swing gets “handsy,” everything starts to leak—flying elbows, bent arms, scoops, and inconsistent contact. The PGM Inflatable Smart Ball Trainer is a quick, portable way to bring your motion back together by training the one thing great swings share: connection.

Place it between your forearms (or upper arms) and you’ll instantly feel how your arms, chest, and body turn are meant to move as one—so the swing becomes compact, controlled, and repeatable. You can adjust the firmness for the feedback you want, and the retractable strap with a one-second lock makes setup fast for warmups, range sessions, or quick reps at home.

Why golfers love it:

• Immediate feedback for a connected swing

• Helps prevent arm bending and keeps correct arm spacing

• Cleans up flying elbows, scooping, and “all arms” swings

• Adjustable firmness for comfort + stronger feedback

• Lightweight, durable PVC—easy to keep in your bag

Instant “feel” for a connected swing
The PGM Inflatable Smart Ball Trainer gives you immediate feedback on arm connection and posture. Place it between your forearms (or upper arms) and it encourages your arms, chest, and body turn to work together—so your swing feels compact, controlled, and repeatable instead of handsy.

Cleans up the common swing leaks
If you fight flying elbows, collapsing structure, scooping, or that “all arms” move that kills consistency, this trainer helps you groove a better pattern. When your arms stay connected and your pivot stays honest, contact tightens up and direction control gets easier.

Correct posture + arm-distance muscle memory
Built to help you correctly grasp the swing posture, this trainer reinforces the proper distance between your arms—so you can fix and strengthen arm-distance muscle memory and avoid arm bending through the swing.
Adjustable firmness, comfortable contact
Because it’s inflatable, you can tune the firmness to match the drill—softer for longer sessions, firmer for stronger feedback. The rounded shape sits comfortably against your arms without feeling like a hard block, making it easier to build the right motion without overthinking it.

Retractable shoulder strap with one-second lock
Comes with a retractable shoulder strap and a one-second lock for faster setup. It’s convenient, quick to adjust, and easy to use during practice sessions or lessons.

Durable, lightweight PVC build
Made from high-quality PVC, it’s durable enough for regular practice while staying lightweight and easy to carry.

Portable practice that fits anywhere
Lightweight, compact, and easy to clip onto your bag, it’s perfect for range days, home reps, warmups, or quick rhythm work before a round. Start with half swings, then build to fuller swings as the connection becomes natural.
