Most are unaware of what a smith machine is and the benefits smith machines provide. There is a bit of controversy over using machines or not, and we will put that to rest here as well.

Too long, don’t want to read? Scroll to the bottom of the blog for a feature comparison chart

A smith machine is a device that allows the user to complete squats, often called smith machine squats, and bench pressing safely without a spotter. The Olympic sized bar is connected to the smith track which sets the bar path and ensures you do not fall forward or backward. The bar is also rigged with a large hook. When the user is done with their workout or feels as if they cannot complete their exercise, the user simply needs to roll the bar to lock the bar in place.

Some argue smith machine squats ruin your form and put too much pressure on certain parts of your body. However, all Marcy Smith Machine Home Gyms account for this potential concern by providing bar catches and weight catches for those who prefer free weight squats. By switching between the two forms of squats, you can see which you prefer while still being able to safely complete your exercise. This is one of the reasons Marcy Smith Machine Home Gyms or Systems are not just called “Marcy Smith Machines”.

Marcy Smith Machine Home Gyms provide a number of other benefits aside from the smith machine itself. The adjustable bar catches and adjustable safety catches (or adjustable safety bar) included with each home gym turns every unit in to a smith machine and power rack / squat cage / Squat Stand in one (depending on the exact model you choose.) 

Marcy Smith Machine Home Gyms all include a bench with an adjustable seat pad that is not attached to the entire unit. Move the bench away from the unit for squats or use the bench with the unit for various presses. You can use the bench with dumbbells (not included) for strength training exercises when not using the entire unit. This is just the start of targeting multiple muscle groups.

In the past, fitness enthusiast needed a gym membership for cable crossovers because the standalone cable machines were so large and expensive. All Marcy Smith Machine Home Gyms include a form dual upper pulley cables. Use the upper pulley cables for lat pulls, cable crossovers, and more. All units also include some form of a single or double lower pulley for rows, curls, and more.

For your convenience, every unit comes with removable Olympic sleeves. As a result, you can use the current Olympic weight plates you own or the current standard weight plates you own on any of the Marcy units – it would just be a matter of having the Olympic sleeves on or off of your system. The convenience of this single piece of home gym equipment does not stop there.

All Marcy Smith Machine Home Gyms have some form of weight storage, but it varies from model to model. Some units have storage pegs for your weight plates while others have a weight plate rack.

We’ve focused on what a smith machine is and the similarities Marcy Smith Machine Home Gyms have. Below, you will find out some of the differences.

Marcy Smith Machine | SM-4008 – the most economical unit by Marcy. This unit features everything noted above. In addition, the SM-4008 has a pec deck, pull-up bar, leg developer, and foot plates for seated rows.

The SM-4008 is ideal for those looking for a full body workout without any of the frills. For many, the absence of a preacher curl pad on this unit is a deal breaker, however, you could always workout your biceps using the lower pulley instead. The unit also has 4 storage pegs for your weight plates.

Included accessories: cable handles, v-bar, triceps rope, ankle strap, and shiver bar

Marcy Smith Machine / Cage System | MD-9010G – is Marcy’s best selling home gym. This unit features everything noted in the blog above. The MD-9010G also has a pec deck, preacher curl pad, leg developer, and foot plate for seated rows.

The MD-9010G is ideal for those looking for a full body workout with the added convenience of linear bearings used for the smith track portion of the unit. The linear bearings make your movements with the smith bar smoother than without linear bearings (like the SM-4008.) For some, the absence of a pull-up bar is a deal breaker, but you can utilize the pulley cables for various lat and row exercises that will workout your back.

Included accessories: cable handles, triceps rope, ankle strap, and shiver bar

Marcy Pro Smith Machine Home Gym Training System Cage | SM-4903 – this unit can best be described as combining a power cage, power tower, and smith machine in to one. This unit features everything noted in the blog above. However, the SM-4903 includes a pull-up bar and adjustable dip bars (which are the stand out features from a power tower.)

In addition to a smith machine, the unit has adjustable bar catches and a safety bar that can be used inside the unit, much like a power cage.

The SM-4903 has dual upper and lower pulleys that run on two different pulley trolleys. As a result, the left side pulleys function independently of the right side pulleys. The two pulley trolley system allows for two users on the SM-4903. Or, you could set different weights on each side and use the unit as a circuit trainer.

For some, the absence of a preacher curl pad and leg developer is a deal breaker. However, this unit is much more fit for someone looking for the convenience of a power tower, power cage, and smith machine in one. And, unlike the other smith machines, this unit has a weight plate storage rack as opposed to storage pegs.

Included accessories: cable handles

Marcy Smith Machine / Cage System with Pull-Up Bar and Landmine Station | SM-4033 – the newest and most stacked Marcy Smith Machine Home Gym. This unit features everything noted in the blog above and much much more. The SM-4033 includes a smith machine, pull-up bar, pec deck, and adjustable dip bars.

Unlike any other Marcy Smith Machine Home Gym, the SM-4033 includes a preacher curl pad with bar rest, landmine attachment, and dual adjustable pulleys. The SM-4033 offers a full body workout with the most variety in one machine. The SM-4033 includes 6 weight plate posts and is the only smith machine to include a bar holder for your Olympic bar.

Included accessories: cable handles, triceps rope, and landmine attachment.

A quick tip for all the models above – always lubricate the moving parts of your smith machine with silicone based lubricant! This will increase the longevity of your unit and ensure your machine works properly for years to come.

No matter which unit you choose, these multi-function pieces of equipment will help you build muscle quickly and efficiently, much like a circuit trainer. Take your weight lifting to the next level and save time with any one of Marcy’s Home Gyms.

  2. I don’t see any information concerning the Marcy Pro Full Cage System MWM-4484. Was this unit discontinued? I would like to know if I paid a fair price. The fitness equipment shortage is making way for alarming price gouging.
