Best Smith Machines For Your Home or Garage Gym in 2019!

updated January 1, 2019

The Smith Machine was actually invented by a man who is known as the father of American Fitness, Jack LaLanne. But it was gym executive Rudy Smith who developed it and had it manufactured for commercial gym use in the mid-1950’s.

The Smith Machine looks like a modified power rack. It consists of a barbell that is fixed inside of steel rails. Vertical posts features a series of hooks onto which the barbell can be placed. During the workout these act as a self spotter, allowing you to bail out of the exercise by simply flicking your wrists.

The Smith Machine is a controversial piece of equipment. It has a lot of haters who claim that it should never be used. Then there are those who swear by it as a powerful and effective muscle builder. We’ll delve into the pros and cons of using a Smith Machine shortly. First, though, let’s identify the best Smith Machine for your home gym.

We have identified the top 5 Smith Machines for home use on the market. Our favorite was the Marcy Diamond Elite. We were also mightily impressed with the units offered by Body Solid, Deltech, Powerline PSM 144X and the Yukon Caribou III Smith Machine.

Smith Machine Reviews

Mercy Diamond Cage

The Marcy Diamond Elite is an impressive looking machine. Much more than a Smith Machine, the Marcy Diamond is a complete workout package that includes padded incline bench, preacher curl attachment and high and low pulleys. Yet the features that set the Marcy apart are its ultra glide linear bearings, the dual function leg developer and a press bar with sealed linear bearings.

The Marcy Diamond Elite features a low pulley with a foot rest to allow you to perform seated rowing type exercises. Thanks to the linear bearings, all of the pulley systems operate with an independent motion system and are extremely smooth and fluid to operate.


  • Smith machine glides up and down freely
  • Very sturdy construction
  • Comes with high and low pulleys and foot plate for seated rows
  • Comes with padded bench and preacher curl attachment
  • Olympic plate storage pegs


  • The Pulley system is quite difficult to set up
  • Slides on carpet
  • Tall guys won’t get a full stretch on the arm attachment


The Marcy Diamond Elite is a fantastic addition to any home gym. Far more than a Smith Machine, it will allow you to perform every cable exercise you’ll ever want while providing the safety and isolation of Smith machine training. Reviewers have been impressed with fast delivery and customer service.​

Body Solid Series 7 Smith Gym

The Series 7 by Body Solid is the culmination of years of design, fine tuning and recalibrating to produce the finest Smith based training system possible. The base is built from a 2 inch by 3 inch commercial quality main frame, set to a 7 reversed pitch. This 7 angle is critical as it allows for more natural upper and lower movements that allow for more precise chest and gluteal stimulation on bench presses and squats.

The Series 7 allows you to do more than 50 exercises. The linear ball bearing Smith pulley system allows for 20 cross-member lockout points. This allows you to bail out of a movement at any point safely and simply. The safeties on this machine are strong and durable, giving you confidence when you need it the most.

The Yukon Caribou III features dual bar holders and safety rail spotter arms. With the Yukon you get the safety and control of a Smith Machine coupled with the freedom and uni-lateral movement of free weights. The machine comes with a lat pull-down unit, and a chin up bar. It also has an integrated dip station mount.

Should You Train with A Smith Machine?

The Smith Machine has received plenty of hate over the years. Naysayers will tell you that it’s not functional, it relies on a fixed plane of motion, it doesn’t require stabilizer muscles and that you can hurt yourself while using it.

But, if you are interested in hypertrophy - muscle growth - the Smith Machine is a smart training choice. However, beginners should not use the Smith machine. They need to build a foundation that integrates their neural motor pattern with the natural movement pattern of the exercise. They can only get this from free weights.

For intermediate and advanced trainees, however, the Smith Machine is beneficial. They have already learnt the proper movement patterns of the muscle and know how to make the target muscle fire.

Why Is An Exercise Easier On A Smith Machine?

Most modern Smith Machines have a pulley system set up to the barbell. This, in effect, reduces the weight of the barbell. However, the old fashioned barbells that do not have a pulley system, are actually heavier than a barbell. With these machines you also have the weight of the hooks as well as the weight of the barbell.

A typical Smith Machine barbell is around 15 pounds of weight when the pulley set up is factored in. However, a free weight barbell is a dead weight of 45 pounds. In effect, this means that when you put a 45 pound plate on each side of the bar, with a Smith Machine you’re lifting 105 pounds, compared to 135 pounds with free weights.​

Free Weights VS Smith Machine

Many people claim that using free weights is far superior to using a Smith Machine. They generally cite the following reasons:

  • Free weights force you to balance and support the weight
  • Free weights engage more stabilizer muscles
  • Free weights puts you in a real 3-dimensional training environment

However, using a Smith Machine will still build muscle. Former Mr Olympia Dorian Yates did his squats and bench presses exclusively on a Smith Machine. And a lot of modern pro bodybuilders use the Smith Machine and achieve phenomenal results.

The Smith Machine allows you to more specifically target the working muscle group. For example when doing the squat, the Smith Machine takes the load away from the accessory muscles so you can focus on the quadriceps. Another huge benefit of using the Smith Machine is that they provide a safety factor that you cannot get with free weights. The Smith Machine has a built in spotter that allows you to bail out if you get in trouble.

One more plus with the Smith Machine is that it allows you to perform partial reps by locking out half way through a repetition. This is great for building up your strength during the weakest part of the the movement.

While you would never want to exclusively train on a Smith Machine, it provides a valuable adjunct to free weight training that every serious trainer needs.

The Smith Machine is especially good for the following exercises:​


A Smith Machine is an excellent adjunct to any home gym. Once you’re already set with a power rack, a quality Smith Machine will allow you to take your training up a notch. The best home gym Smith Machine we came across was the Marcy Diamond Elite, which gives you so much more than simply a Smith Machine. For the budget conscious, you can’t look past the Powerline PSM 144X by Body Solid.
