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. The machine does include two catch bars and two safety bars, which give you the possibility 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 bars of the Smith machine and the Smith bar itself 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 with proper care. 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 when it comes to padding.
The machine’s pulleys are 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.
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 the storage pegs are compatible with both Olympic and Standard bars. Unfortunately, this machine does not have a Lat Bar accessory either. In addition, if you’re wondering, the bench is not compatible 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 also has removable catch bars and safety bars opposite the Smith machine so that 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 it’s slightly shorter. Therefore, you will have to add more plates to it to make up for this difference.
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 of all, 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 parts that need assembly.
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 and check for loose bolts periodically.
