The SMITH 3D Trainer™ (S3D) is an evolutionary strength training system, marking a major advancement in barbell training technology. Unlike traditional Smith machines that feature only a fixed linear range of motion (ROM), the S3D’s primary advancement is a multi-directional ROM that mimics the natural travel path of an Olympic barbell.

Made in the USA

Natural Barbell Path of Travel

The S3D moves the way you move. Unlike traditional Smith machines that follow only a single linear bar path, the S3D is the ultimate training partner.

Safety Redefined

Synchronized safety catches enable self-spotting throughout the entire exercise. The S3D eliminates the noise and intimidation factors associated with bar drops and common squat rack re-racking.

Unique Pre-load Adjustability

Achieve your ideal starting point for lift off. The S3D pre-adjustment capability allows for perfect positioning before every lift without the need to compromise your form.

Strength Training is on the Rise

Barbell training reigns supreme as the gold standard for building strength and muscle. It fosters proper form, adapts to any experience level, and offers unparalleled versatility. But even the most dedicated lifters know its limitations: takeoff positioning, safety concerns, and space constraints can hinder progress and experience.

The SMITH 3D Trainer replicates barbell movements with improved safety, control, and space optimization. Transition effortlessly between exercises, building strength and muscle mass optimally. The synchronized safety catches adapt to every path of movement, offering peace of mind for both beginners and experienced lifters.


Move with Safety

The S3D’s synchronized safety catches allow for self-spotting throughout the entire range of motion during exercise. The patent-pending carriage system enables a natural free-weight experience.



Assist clients with form correction with increased visibility of movement patterns thanks to the S3D’s open design and without the simultaneous requirement of spotting.


Noise Abatement

Significantly reduces the sound and vibration associated with excessive bar drops and re-racking of squat, deadlift, and bench press movements.
