Converts Your Rack Into a Full Smith Machine: Turn almost any rack into a safe and versatile Smith system for controlled strength training.
Use any Olympic or Selected Specialty Bars: Works with your existing barbell. Quick release mechanism locks and unlocks in seconds.
Built for True Low Body Workouts: Offers the lowest starting position of any modular Smith setup for proper depth on hip thrusts, deadlifts, lunges, squats, and more.
Smooth, and Stable Movement: Precision bearings and a split-rod design create a controlled, friction-free feel while supporting future upgrade options.
Broad Rack Compatibility: Fits all 3x3 racks. Also works with select 2x3 racks that use 1-inch or 5/8-inch holes. Pass-through bracket adjusts easily to different rack heights.
Space Saving Design: Attaches to a single upright and stays close to the rack to keep your training area clear.
The BOB lets you transform the rack you already own into a complete guided-lifting system. Instead of buying a giant separate machine, you attach BOB to your rack and instantly gain the stability and controlled movement normally found in commercial gyms. This helps you lift with more confidence because the bar moves in a steady, predictable path every time. It’s perfect for anyone who wants a safer and more secure way to train without adding another huge piece of equipment to their space.
Works With Your Favorite Barbell
Unlike traditional smith machines that force you to use the built-in bar, the BOB lets you use the barbell you already love. That means you can switch between different types of bars depending on your workout: straight bars, selected specialty or training bars. Changing bars takes only a few seconds, so you’re free to adjust your routine without slowing down. This gives you more control over how you train because your bar choice can completely change the feel of an exercise.
Smooth, Easy Movement for Every Lift
The BOB is designed to move up and down smoothly so your lifts feel controlled and comfortable. This makes it easier to focus on good form since the bar won't shake, shift, or pull you off balance. Because the movement is guided, it’s especially helpful for beginners learning new exercises or lifters recovering from injuries who need extra support. Since the BOB provides the lowest training position of any modular Smith system, it lets you perform lower-body exercises like hip thrusts, deadlifts, lunges, and deep squats with full depth.
Unparalleled Safety Features
The BOB Smith system is built for safe and confident lifting every session. Its solid inner-mount crossmembers and front foot keep the rack stable, reducing wobble and ensuring smooth bar movement. The quick release mechanism for the barbell allows you to easily and safely rack or drop the bar when needed, giving you control at all times. Together, these features create a reliable setup that prioritizes your safety while you train.
Saves Space and Stays Out of the Way
Most smith machines take up a huge amount of floor space, but the BOB is different. It attaches directly to your rack, so it barely uses any extra room. When you’re not using it, it stays off on both sides so your rack remains fully open for other exercises like squats, pull-ups, and bench work. This makes it an ideal choice for garages, small rooms, or shared spaces where every inch counts. You get all the benefits of a full machine without cluttering your gym.
Built to Grow With Your Home Gym
The BOB is made for people who like equipment that can be customized and upgraded over time. It works with almost any 3x3 and selected 2x3 racks while it doesn’t lock you into special parts or one fixed way of training. As your gym grows, the BOB grows with it, whether you add new attachments, try new training styles, or switch to different barbells. It gives you the same level of flexibility and variety you’d expect in a large commercial gym but in a simple, rack-mounted design that fits your space and your goals.

Top - Notch Performance in a Compact Footprint
The BOB gives you all the benefits of a full-size smith machine without eating up your floor space. It mounts neatly to your rack, stays close to your uprights, and replaces the need for an expensive, oversized standalone unit.
Total Barbell Freedom
Most smith machines force you to use their built-in bar, which often feels awkward, oversized, or just not right for the movement. The BOB lets you choose your own bar, giving you control over diameter, knurling, whip, and specialty options for endless training variations.
Unmatched Range of Motion & Adjustability
From incredibly low start positions to fully extended overhead movements, the BOB covers more training angles than standard fixed-path systems. With adjustment points every 2 inches and a quick-release system, you can set up faster, start lower, lift heavier, and train exactly the way you want.
Yes. The BOB works with any standard 3x3 rack that uses 1” or 5/8” holes. Its pass-through bracket also makes it adaptable to racks with varying heights.
Absolutely. That’s the entire design philosophy behind the BOB. Any Olympic-size barbell can be mounted using the quick-release system.
Your barbell will fit on the Bob when it meets the 3 criteria below:
Your barbell shaft diameter is within 25mm to 32mm in diameter.
Your barbell can be mounted on a normal squat rack.
Your barbell mounted on a normal squat rack with jcups, looks level and not angled.
Yes. The BOB is engineered for an extremely low start height, making it perfect for hip thrusts, deadlifts, rows, and any movement where starting low matters.
Yes. BOB can be installed on either side of your uprights, depending on how you prefer to train or how your gym is laid out.
The BOB uses precision bearings and a split-rod system for ultra-smooth travel. The split rods also reduce shipping costs and support future upgrades.
When the bar is secured using the hook and clips, it adds about 17 lb to the total weight of the barbell.
The BOB integrates smoothly with our very own squat racks, giving you a flexible Smith Machine setup no matter how your home gym is built. Here's how the Bob Smith Machine can be configured using the Osprey Rack and the Garage Series Rack with Pull-up Bar.
The 1" Shorter Setup using the Osprey Rack
On the Osprey, you can mount the BOB on the inside by removing a single guide rod, keep the outside of your rack usable, and only sacrifice a small amount of range of motion.
The 5/8" Shorter Setup using the Garage Series Pull-up Bar
While on the Garage Series rack and other smaller racks, the BOB still fits comfortably, making it perfect for compact home gyms and allowing you to reposition it easily for a mobile Smith Machine experience.
