One of the best gyms for home use is the Marcy SM-4033 Smith Machine, an all-in-one strength training machine. It offers everything you need to build muscle, get strong, and burn fat. In addition, it can train all major muscle groups and give various exercises for other smaller muscle groups.

The smith machine bar allows you to perform squats, deadlifts, presses, and rows in assisted and safe environments. This feature is excellent for the very weak or if you’re looking to train heavily while alone; it has safety stops that allow you to escape safely from the bar whenever needed.

To add to the convenience, the Marcy SM-4033 Smith Machine comes with several attachments – Short Bar, Triceps Rope, Cable Handle (2), and a Land Mine attachment.

SM-4033 Cage construction

The Marcy SM-4033 Smith Machine features heavy-duty 14-gauge steel tubing construction. Most frames come with a durable, corrosion-resistant, and chip-resistant paint finish. However, the guide rods of the Smith element and the lat machine come chrome-plated. It also stands for the adjustable posts of the crossover adjustable pulleys.

The fully assembled cage is reasonably large. It is approx—70″ (178 cm) deep and 67.8″ (172 cm) wide at the base. However, considering the barbell, the total width of the unit is 84″ (213 cm). The highest point of the cage is the top of the pull-up bar assembly, which reaches approx—86″ (219 cm) above floor level.

Thus, the smith machine won’t fit in a room with a 7-foot ceiling. Plus, you must allow at least one foot of clearance above for the correct execution of all pull-up exercises. Marcy advises leaving two feet of room on each side and the rear and at least three feet – 4 feet in the front.

The whole Marcy SM-4033 smith machine is pretty heavy. Its total weight is close to 600 lbs (272 kg). However, all this weight, plus the extra weight the loaded plates provide, delivers superior stability. The unit shouldn’t budge even if you use weight loads close to the maximum limit. In addition, the base bars have anchor points, so you can secure them to the floor if needed.

The front upright bars of the cage feature 17 adjustment holes for the j-hooks and dip bars. They are 1 inch in diameter, so other standard attachments should be compatible with this Marcy home gym.

Workout stations

The Marcy SM-4033 Smith Machine makes available five main workout stations. These are:

Smith cage. The smith cage is the primary workout element of the Marcy SM-4033. A 7-foot Olympic bar comes included with it. It offers the possibility of performing secured squats or deadlifts with extra control instead of free barbell exercises. The front pillars of the cage also have attachment holes for j-hooks if you want to perform free squats. However, safety bars do not come included. Only the Smith element has safety hooks.

Pull-up station. This attachment consists of a multi-grip bar. It offers the possibility to perform all kinds of pull-ups or chin-ups and is durable enough to support weighted exercises. Its grips do not have foam sleeves. However, they come knurled for improved contact.

Crossover station. This workout station consists of two mobile pulley attachments. Their upright posts feature 15 adjustment positions. They offer an inner swivel of 90°, and their carriages have handles for easy adjustment. They offer the possibility to execute cable crossover exercises, lat pulldowns, standing rows, shoulder presses, and more.

Butterfly press. This attachment is quite a plus. It consists of two arms with large pads and a backbone with an extra backrest pad. It attaches to the lat machine and offers the possibility to perform butterfly exercises. However, it does not work as a front press, as is the case for the butterfly elements of other home gyms.

Low pulley station. The unit’s low pulley attaches at the base of the lat attachment. It offers the possibility of performing seated, standing, and other low pulley exercises. The machine also includes a footrest plate for extra support during seated rows.

It is important to note that the low pulley cannot attach to the included bench to perform leg extensions or curls. However, with the provided ankle cuff, you can perform standing (one leg) curls via the crossover station.

SM-4033 Other parts and accessories

The Marcy SM-4033 Smith Machine comes equipped with 31 pulleys. These are heavy-duty nylon materials, highly resistant to abrasion, and sealed bearings for smooth motion.

The included cables are steel ropes with PVC sleeves on them to prevent the scratching of the pulleys. Although most of the machine’s stations have a maximum of 300 lbs (136 kg) of weight loads, the cables have a  2,000 lbs (907 kg) weight load.

This Marcy SM-4033 home gym doesn’t have safety bars for free squats. However, a set of j-hooks come included with it. They are rubberized to prevent noise and paint damage. And have a maximum of 300 lbs (136 kg) weight load.

A set of two dip arms also come included with the Marcy SM-4033. These attach to the front upright pillars of the cage. They have extended grips with rubber sleeves at the front for improved contact.

Six weight storage posts come included with this Marcy strength cage. They attach to the rear upright post of the unit. They’re for storing 2″ Olympic plates; they do not have removable sleeves and cannot accommodate 1″ standard plates. Collar springs for securing the plates come included for all storage posts.

Last but not least, the Marcy SM-4033 includes a landmine attachment, a lat bar, a tricep rope, 2 D-handles with multiple attachment rings, a short bar, and an ankle strap.


The Marcy SM-4033 home gym system includes a multi-position adjustable bench with a preacher pad attachment. The bench has a steel frame coated with a corrosion-resistant paint finish. It is approx. 62″ (158 cm) long and 26″ (66 cm) wide, while its highest point reaches 55″ (140 cm) when the backrest is at the top position.

The bench offers six adjustment positions for the backrest. The approximate angles are -27°, 0°, 12°, 27°, 42°, 59°, and 76°. The seat pad is also angle-adjustable. It offers three positions 0°, 8°, and 16°.

The bench’s adjustability doesn’t end here. Its preacher pad attachment and the height of the ankle stopper are also adjustable. Each one has three height adjustment positions.

The backrest, the seat pad, and the preacher pad integrate 2.5″ foam cushioning. Their covers are made of a durable vinyl material that is sweatproof and easy to maintain. In addition, the preacher pad features support for your curl bar. Its exact weight limit is not specified, but it should hold at least 100 lbs (45 kg). The ankle stoppers also have foam rollers to provide comfort during sit-ups.

The exact weight of the bench is not specified, but it is pretty heavy. However, its rear base has a set of small wheels, while the foot stopper attachment has a handle so you can easily lift the bench from its front end and roll it away if the cage is empty.

SM-4033 Weight Capacity and Resistance

Most training stations with the Marcy Smith Machine SM-4033 have a maximum weight limit of 300 lbs (136 kg). Thus, it includes the Smith element, the weight carriage of the lat attachment, bar catches, dip bars, and pull-up bar attachment.

The bench has a maximum weight limit of 600 lbs (272 kg), including the user’s weight plus the barbell. The weight plate storage posts have a limit of 100 lbs (45 kg) each.

The machine’s butterfly press and the low pulley provide a 1:1 weight ratio in weight resistance. Therefore, if you load the lat carriage with 100 lbs (45 kg), you will benefit from a weight resistance of 100 lbs (45 kg) when using the low pulley or the butterfly station.

Marcy SM-4033 Smith Machine

Conversely, the crossover pulleys have a weight resistance ratio of 2:1. Therefore, if the carriage has 100 lbs (45 kg), each crossover pulley will provide a weight resistance of 50 lbs (22. 6 kg).

SM-4033 Assembly and Maintenance

Marcy SM-4033 Smith Machine
Marcy SM-4033 Smith Machine

The Marcy SM-4033 Smith Machine requires complete user assembly. It comes in 5 heavy boxes and requires at least two people for transport and assembly. The assembly task is difficult due to the number of parts and will take at least 5-6 hours.

On the other hand, the manual provides clear, step-by-step assembly instructions and schematics. The tools for the assembly do not come included with the machine. You will need two adjustable wrenches and a set of Allen wrenches.

Once completely assembled, maintenance does not require much. However, the guide rods of the Smith element and the lat carriage may require some greasing from time to time to provide a smooth trip for the moving parts. Inspecting the machine for loose parts and retightening as needed is also advisable.

  1. This Marcy SM-4033 Smith Machine is the real deal.  I came up with that thought due to the fact it is about 272 kg in weight. The bench is fully reclinable and helps work out with dumbbells or free weights.

    This is truly a heavy-duty machine that will suit any home gym.  However, I live in a one-bedroom apartment and don’t have the space needed for this gym.,

    Someday, when I live in a larger house, I would like to have this Marcy Smith Machine as part of my home gym.

    Thanks for this article. I found it very informative.

    • Hi Stella, thanks for taking the time to read about and comment on the Marcy SM-4033 Smith Machine. I hope that you’ll be able to build your home gym sooner rather than later. Reach out to me if I can be of any assistance.

      Kind regards, Robert

  2. I concocted that idea because of the reality it is around 221 kg in weight. The seat is completely reclinable and assists workers with the trip with hand weights or freeloads.

    This is really a rock-solid machine that will suit any home rec center. In any case, I live in a one-room loft and don’t have the space required for this rec center.,

    Sometime in the future, when I live in a bigger house, I might want to have this Marcy Smith Machine as my home rec center component.

    A debt of gratitude is for this article. I thought that it was useful.

    • Hi Herman, thanks for taking the time to read and comment on the Marcy SM-4033 smith machine review. What do you do for exercise until you live in a bigger house? Let me know if I can be of assistance.

      Best regards, Robert

  3. Wow, this is a great machine. I like this a lot because you can do more than 50 exercises. And the bench has transport wheels which are also very important. And especially the 600lbs capacity bench. Thank you very much for this valuable detailed review of the Marcy SM-4033 Smith Machine.

    • Hi Pasindu, 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

  4. Hey Robert,

    One of the most significant benefits of the SM-4033 is that it comes with a functional trainer station, a fancy term for the pulleys. With dual, adjustable pulleys, you can perform cable crossovers from any angle, but you can also perform a wide array of lifting, twisting, and isolation exercises.

    Thanks for this great review.

    • Hi Kayamba, 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
