SM-4008 Frame Construction

The Marcy SM-4008 Combo Smith Machine frame is 14 gauge square steel tubing, offering excellent sturdiness and stability. Although its base bars do not have holes for anchoring them to the floor, this isn’t necessary, especially if you load the storage pegs with weight plates.

This Marcy home gym system is relatively large. Without the bench and the Smith bar attached, the cage itself is approx. 66″ (168 cm) long and 60″ (153 cm) wide. With the bench attached, its length will become 94″ (239 cm), while the Smith bar is 80.75″ (205 cm). The fully assembled machine’s highest point is 84″ (213 cm) for its height. Thus, it’s advisable to place it in a room with at least eight ′.

The Smith bar is not an Olympic bar. It weighs only 25 lbs, and it’s slightly shorter. However, it features Olympic sleeves, which are removable to accommodate Standard weight plates.

The main upright bars of the frame feature nine locking positions for safety and catch bars. In addition, the machine includes two catch bars and two safety bars, allowing you to exercise with the bar outside of the Smith machine.

The top part of the machine includes a pull-up bar. This bar is reasonably straightforward; it does not have any rubber grips but does offer the possibility to perform wide-grip pull-ups.

Finally, most of the bars in the frame construction come with a gray, corrosion-resistant finish. However, the Smith machine’s bars and the bar are chrome coated.


The bench supplied with the Marcy SM-4008 Smith machine features a metallic frame similar to the cage frame. It can connect to the main structure, but you can also use it without attaching it to the frame. Also, it is removable if needed. Its backrest features four adjustment positions. The bench offers three incline positions and a horizontal position as a general idea.

The bench and the backrest board attached to the mainframe integrate a generous layer of high-density foam, providing optimal comfort. The upholstery is two-toned, brown vinyl, which can last a lifetime if treated properly. The leg developer station attached to the bench features four 3.5″ (8.9 cm) foam rollers to deliver the required comfort for various leg exercises regarding padding.

SM-4008 Pulleys

The machine’s pulleys are made of heavy-duty nylon material and integrate sealed ball bearings for smooth operation and a long lifespan. The cables have a much higher capacity than the machine’s weight capacity. A sheet of PVC also covers them to deliver a smooth movement over the pulleys.

Included accessories

The main accessories included with this machine are:

  • Handle grip x2
  • Triceps rope x1
  • Ankle strap x1
  • V bar x1
  • Shiver bar x1
  • Chain link x1

The machine does not include weight plates of any kind. However, its bar and storage pegs are compatible with Olympic and Standard bars. Unfortunately, this machine does not have a Lat Bar accessory either. In addition, if you’re wondering, the bench is incompatible with a Preacher Pad attachment.

SM-4008 Workout stations

Chest press station. This workout station involves the Smith machine and bar. However, the Marcy SM-4008 has removable catch bars and safety bars opposite the Smith machine so you can work with the bar outside the cage.

Pec fly station. This workout station involves two simple arms with elbow pads, using the rear weight bar. Specifically, this station is for workouts focusing on developing pectoral muscles.

Pull-up station. This feature is the pull-up bar integrated into the top part of the machine. It’s a simple bar without knurled or rubber grips, allowing various pull-up exercises.

High crossover station. Two high pulleys give this exercise station for crossover exercises or lat pulldowns. The machine does not include a lat bar accessory, but you can purchase one separately, attach it to the pulleys, and perform lat pulldowns.

Leg developer. This element is attached to the machine’s bench. Specifically, it offers the possibility to perform leg extensions and leg curls;

Low pulley station. The low pulley opens many exercises, such as one-legged curls, abductions, or seated rows. With this in mind, an ankle strap and a slight shiver bar are (supplied) for the various activities you can perform on this pulley.

Weight Limits and Ratios

Like most other weight machines involving a pulley system, the weight resistance delivered by the workout stations of the Marcy SM-4008 varies. Therefore, here are a few of its weight ratios:

  • Fly station – 10 lbs load generates 5 lbs of resistance.
  • Left Cross-Over – 10 lbs load produces 5 pounds of resistance.
  • Right Cross-Over – 10 lbs load produces 5 pounds of resistance
  • Low pulley – 10 lbs load has 10 pounds of resistance

Regarding the included Smith bar, it is not a regular Olympic bar. It weighs only 25 lbs (11.3 kg) and is slightly shorter. Therefore, you will have to add more plates to compensate for this difference.

Marcy SM-4008 Combo Smith Machine

The machine’s bench has a weight capacity of 300 lbs (136 kg) in terms of weight limits. The other weight limits are 300 lbs (136 kg) for the Smith bar, 200 lbs (90.7 kg) for the crossover station, and 100 lbs (45.3 kg) for the leg developer.

SM-4008 Possible Exercises

SM-4008 Assembly and Maintenance

First, just like any other Smith machine, the Marcy SM-4008 is a substantial piece of equipment, so its transport and assembly require at least two people. The assembly process isn’t too complicated, but it may take several hours due to the many necessary parts.

However, the provided manual offers pretty clear step-by-step assembly instructions and diagrams. Unfortunately, the tools required for assembly do not come with the machine. Instead, you’ll need two adjustable wrenches and a set of Allen wrenches.

On the other hand, the maintenance doesn’t require much once assembled. You have to grease the moving parts, check for loose bolts periodically, and retighten them as needed.

  • Several workout stations, including chest press station, pec fly station, low pulley station, high pulley crossover station, leg development station, pull-up bar;

10 thoughts on “Marcy SM-4008 Combo Smith Machine | Excellent for Home Use”

  1. Hi there. Thank you for sharing your review of Marcy SM – 4008 Combo Smith Machine. From all indications and everything you’ve shared about this machine, I feel that this machine is an excellent option. Because it lasts for years (and also has a two years limited guarantee), it has several stations and different exercises can be done with it, it’s affordable and has lots of features. I haven’t seen a large home gym like it before.

    Take care and compliment of the season.

  2. If only I saw this machine two months ago, I wouldn’t have bought the ugly one that I have right now. Compared with this one, which looks sturdy, the one that I have bought isn’t as good. The screws have loosened now after a month of use. Well, it’s a lesson learned, and next time I will buy an all-in-one home fitness equipment, it will be this. I will bookmark this review for future use of the link.

  3. The Marcy SM-4008 looks like a fantastic machine.  The fact that weight plates do not come with the machine does not make any difference.  I have some neck and shoulder problems which means the I cannot do bilateral exercises for my upper body.  I need to do one side and then the other.  The pulley system on this machine is perfect for that.  I can do bilateral leg exercises.  The one problem I see with this incredible machine is that there is not a lower pulley system for something like shrugs or curls.  Thanks for the review of this machine.  I am hoping that I might modify it a bit.

    • Hi Anastazja, thanks for stopping by and sharing your thoughts with us. May I suggest the Marcy MWM-4965 home gym for about half the cost? In addition, it does not take up nearly as much room as the Marcy SM-4008 smith machine.

      Would you please let me know if I may further assist you with exercise equipment? I’m always happy to help.

      Kind regards, Robert

  4. The Marcy SM-4008 seems to be a well-built machine that a person could use for light to moderate training. You can either go with a light regimen for normal fitness levels and turn some fat into muscle. The moderate regimen will allow you to build strength up to a point, but you will have difficulty in producing massive power since you don’t have the heavier weights.

    This Marcy gym is an excellent machine to help you keep in shape. I would buy this machine for my weight maintenance and overall health management. My doctor has advised that I become more active to reach my goals. This machine looks as if it could do the trick.


    • Hi Jerry, thanks for stopping by and sharing your thoughts with us. Would you please let me know if I may further assist you with exercise equipment? I’m always happy to help.

      Kind regards, Robert

  5. This Marcy combo smith machine is an excellent option for durable and sturdy equipment. I appreciate the 100 exercise options and the pull-up bar included. It would be a perfect choice for home use. It’s definitely on the pricier side, but it’s worth the investment if you’re looking for quality home gym equipment.

    • Hi there; thanks for stopping by and sharing your thoughts with us. Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

  6. Thank you for sharing your review of the Marcy SM-4008 Combo Smith Machine. It sounds like a versatile and practical piece of equipment for home gym use. However, I’m curious to know if you have any tips for beginners considering purchasing a Smith machine for the first time to get the most out of their workouts and ensure proper form and safety.

    • Hi Miki, thanks for stopping by and sharing your thoughts with us. I suggest getting a personal trainer to work with you until you develop proper form and learn how to use the machine safely. 

      Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

      Kind regards, Robert
