One of the most efficient ways to build a home gym is to get gym equipment that’ll maximize all your workout possibilities and take up the least space.

Enter the Marcy Pro Smith Machine 4903.

As a trainer who assists several clients from their homes, I wanted to get an unbiased opinion on this all-in-one Smith machine. So, we bought one here at TotalShape and had our clients try it in a room that mimicked a home/garage gym.

We put this review together based on their experience and all the testing data we collected.

What Is the Marcy Pro SM-4903?

The Marcy Pro SM-4903 is an equipment that combines a Smith machine with precision linear bearings, an Olympic weight rack, a dip station, and a cable-routed pulley system.

It combines all these exercise machines into one attractive and compact design.

The Marcy Pro is forged with heavy-duty steel construction and a durable powder coat finish.

This fine piece of machinery can easily handle up to 600 pounds of weight, and it’s a perfect home gym system for beginner and intermediate lifters looking to build strength and gain muscle at home.

Note: Since the product name’s a bit of a mouthful, we’re going to refer to it as the SM-4903 or the Marcy Pro for most of the remainder of the article.

What Are the Marcy SM-4903 Workout Stations?

The SM-4093 workout stations are the Smith machine, power rack, cable pulley system, pull-up-bar, dip bar, and adjustable weight bench.

Here’s everything you need to know.

1. Smith Machine

Your average powerlifter might not be the biggest fan of even a highly-rated Smith machine; however, they’re an excellent option when used the right way (especially if you’re training alone).

The best feature of the SM-4093’s Smith machine is the smoothness of its glide. At no point did clients feel any weird sticking points or friction, which allowed them to crank out their reps comfortably.

The Smith machine comes with a highly essential safety feature: evenly spread-out steel lockout points. This means that if you fail mid-rep, all you need to do is turn your wrist 30 degrees and re-rack at the nearest lock-out point.

Another thing to note is the barbell. The amount of knurling on the bar is enough to keep your hands from slipping out, especially when your palms are sweaty.

And while the weight limit on the bar is perfect for beginners and intermediate lifters (~300 lbs), we wouldn’t recommend lifting beyond that.

“I’ve found the smith machine to be one of the best ways to overload single arm Zercher squats in a safe and effective method.”

- Dr. Joel Seedman, PhD in Kinesiology

2. Power Rack

Another great feature of the SM-4903 is the power rack, because it’s rare to find home gym systems that include a Smith machine and a good power rack.

The SM-4903 comes loaded with full-length safety stoppers that support 300 lbs (136 kg) weight drops.

However, the most common complaint was the standard spacing (2 inches) for the barbell height.

Many of our powerlifters preferred Westside spacing (1 inch) as it helped them get the perfect height on the barbell.

However, the same lifters appreciated the band pegs at the bottom of the rack, which allowed them to add resistance band training to their squats and bench press.

3. Cable Pulley System

The Marcy Pro comes with four pulleys (two high and two low). Each side supports a total weight of 150 lbs (68 kg) for a total of 300 lbs (136 kg).

The overhead home gym pulley system has two swivel pulleys that are smooth and give constant tension for exercises like lat pulldowns and tricep extensions. The two lower pulleys are just as smooth and perfect for cable rows, lat raises, and bicep curls.

Like the Smith machine, our clients found the cable system smooth and without any friction.

However, the only complaint came from intermediate and elite lifters who were used to performing lat extensions of over 170 lbs (77 kg).

4. Pull-Up Bar

In addition to free weights, a power rack, and a Smith machine, the Marcy Pro comes with a multi-grip pull-up bar for all you calisthenic enthusiasts out there.

You can do pull-ups with neutral, pronated, supinated, and wide grips. According to a study on PubMed, this allows for a wider range of muscle activation [1].

However, if you’re above 6 feet, you may have to curl your hamstrings when using the bar.

5. Dip Bar

A home gym wouldn’t be complete without a proper dip station, especially for those who love calisthenics.

You can customize the height of the dip bar—a feature that our taller clients appreciate.

However, the width of the bars was fixed, limiting clients' ability to perform dips with width variations.

6. Adjustable Weight Bench

The adjustable weight bench is one of the most remarkable features of the SM-4093. It makes your training sessions more targeted by helping you achieve better muscle growth from bench pressing at different angles [2].

The bench has six backrest positions: 0°, 13°, 26°, 40°, 55°, 79°

It also has three seat positions: 0°, 8°, 15°, 22°

Clients who trained using supersets for their chest workouts found the adjustable seating very convenient when switching workouts.

The only downside to the bench is that it doesn’t have a leg developer for hamstring curls and quad extensions.

What Exercises Can I Do With a Marcy SM-4903?

Exercises that you can do with a Marcy SM-4903 are squat variations, glute bridges, hip abductions, cable kickbacks, good mornings, deadlifts, and calf raises variations, among others.

For many of our clients, the SM-4903 was the only piece of home gym equipment they needed because it allowed for various upper-body and lower-body workouts.

Here are some of the many exercises you can perform with the Marcy Pro, making it a good addition to your home gym:

  • Quads: Multiple squat variations like the back squat, front squat, and hack squat. Other quad burners include lunges, standing leg extensions, and step-ups.
  • Glutes: Kneeling squats, glute bridges, hip thrusts, hip abductions, and cable kickbacks.
  • Hamstrings: Good mornings, stiff-leg deadlifts, and Romanian deadlifts.
  • Calves: Calf exercise variations like seated, standing, and reverse calf raises.
  • Traps: Deadlifts, rack pulls, shrugs, and high rows.
  • Chest: Multiple chest workouts like incline press, decline press, flat press, and reverse-grip press; dips and dumbbell flys.
  • Lats: Pull-ups, chin-ups, lat pulldowns, lat pushdowns, cable rows, barbell rows, and dumbbell rows.
  • Abs: Hanging leg raises, hanging knee raises, sit-ups, cable crunches, cable wood chops, and side bends.
  • Shoulders: Standing overhead press, seated shoulder press, behind the neck press, upright rows, lateral raises, face pulls, and rear delt flys.
  • Triceps: Close-grip bench presses, skull crushers, overhead extensions, tricep pushdowns, and tricep kickbacks.
  • Biceps: Multiple curl variations like standing cable curls, overhead cable curls, dumbbell curls, hammer curls, and reverse curls.

As you can see, the Marcy Pro allows you to target the entire body. Many clients seemed happy about the fact that they could get a full-body workout from just one machine in the home gym.

Marcy Pro Sm-4903 Pros and Cons

Here are some of the pros and cons of the Marcy Smith Machine based on various online reviews and the experiences of clients who’ve used it.

  • The weight bench supports 600 lbs (272 kg), with six backrest positions and six seating positions
  • Made with a heavy-duty steel frame that’s reinforced with a durable powder-coated finish
  • Has smooth ball bearings that allow for a smoother lifting motion
  • Has a multi-grip pull-up bar that allows users to perform multiple pull-up variations
  • Comes with full-length and durable safety spotters for when you’re training alone
  • Weight capacity is only 300 pounds, so it’s not the best option for heavy intermediate and elite lifters
  • Doesn’t come with weight plates
  • Not the best option for people above 5”10

Is the Marcy Pro SM-4903 Missing Anything?

A person writing down on a clipboard

Yes, the Marcy Pro SM-4903 is missing a few features.

Although these didn’t affect the quality of experience for clients who used the machine, many users agreed that this Smith machine would’ve been perfect if not for the following:

  • It doesn’t come with any weights (you need to buy them separately).
  • The SM-4093 has a user height limit. Users above 6’3” couldn’t comfortably use the machine for squats.
  • The bench lacks a leg developer for leg extensions and hamstring curls.

We also had some clients who were skeptical of the Marcy Pro because they felt the stability of the Smith machine wouldn’t be optimal for their strength-training.

However, when used correctly, a Smith machine can give you the same level of resistance training as a free weight rack [3].

“[The Smith Machine] allows for you to attempt heavy lifts without a spotter and keeps the barbell on a guided path — which is a disadvantage for some lifts but a plus for others.”

- Anthony O'Reilly, Certified Nutrition Coach

Where Can You Buy It?

Who Should Buy the Marcy Pro SM-4903?

Beginner and intermediate lifters who want an all-in-one fitness product for their home gyms should buy the Marcy Pro SM-4903. Based on my personal experience, I've seen both beginner and intermediate lifters make full use of this machine.

Also, given this Smith machine’s safety features, lifters who live alone (meaning they work out without a spotter) should go for this product.

Who Shouldn’t Use It?

Anyone above 5’10” or whose workout regimen involves squatting reps of 300 lbs shouldn’t use the Marcy Pro SM-4903.

That’s not to say people above 6 feet cannot use the product.

We don’t recommend they use it because it might impede their lifting experience or, at worst, pose certain risks.

Delivery and Shipment

The Marcy Pro ships within 1–7 days after purchase if you order from their website. In our experience, delivery includes only curbside drop-off.

So make sure you have some hands on deck to carry the boxes inside.

The shipment comes to you in four separate boxes. Be warned, if you miss your delivery, you might have to pay a fine to get another appointment.

Customer Reviews

A person looking at his phone at a gym

Based on various online reviews, here’s what customers had to say about the Marcy Pro.

This is an awesome piece of equipment there is so much you can do squats, pull ups, cable crossovers, bench press, dead lifts.....etc and so much more I strongly recommend this product to anyone who is looking to buy a Smith machine. For the house this product is affordable and is also a great size.

- Peter L. from USA

Machine is great — very sturdy and does exactly what it’s supposed to do. The only thing which I guess there’s not getting around is the bench. The bench is great for everything except for flat chest press. The wedge in the seat is huge, and I have to fill it in with a towel.

- Joshua Jordan from USA

The maximum height you can set the squat rack bars is 52”, which is perfect if you are 5 ft 5”. Essentially, anyone taller either must start their squat at 3/4 or drill new holes in the rack to accommodate raising the squat rack mounts — huge oversight by the manufacturer. If you’re handy with tools, a metal 11/16” step bit can be used to modify (drill more hopes) for average-height men. I’m 5 ft 10”, and without modifications, this squat rack would have been terrible.”

- Kris K. from USA


A person online shopping at a gym on her phone

We compared the Marcy Pro SM-4903 against its competitors: FORCE USA Monster G3 Smith Machine, Rogue’s SLM-6 Monster Lite Weight Stack Slinger, and Body Solid Series 7 Smith Machine.

Here’s what we found.

The Marcy Pro outdid FORCE USA in almost every feature. In fact, FORCE USA’s Smith Machine doesn’t come with its own bench, making Marcy a preferred option.

However, it does have a smaller footprint, so it could be a better option for smaller home gyms.

We also compared Marcy Pro to Rogue’s SLML-6 Monster.

Rogue’s product didn’t come with a Smith machine, but in terms of the cable pulley, it outdid the Marcy Pro. It had a 300-pound weight stack, allowing intermediate and elite lifters to go heavy.

Additionally, it can also be drilled into the floor, adding extra safety to your lifts.

The third option, the Body Solid Series 7 Smith Machine, proves advantageous for those on a budget who primarily focus on exercises like Smith machine squats, deadlifts, and bench presses.

This machine offers numerous height adjustments and comes with included weights, which should suffice for most home gym enthusiasts in the initial stages.

However, it's worth noting that the Marcy Pro boasts a higher weight capacity compared to the Body Solid Series 7.


Is Marcy a Good Brand for Weights?

Yes, Marcy is a good brand for weights. Marcy offers a wide range of exercise products—like Smith machines, multigyms, and weight benches—that are strong and durable and offer great value for money.

How Much Does the Marcy Pro Smith Machine Bar Weigh?

The Marcy Pro Smith machine bar weighs between 16 and 36 lbs, depending on the product you choose. Most have a bar weight of 16 lbs, whereas the SM-4033 model’s bar weighs about 36 lbs, and the Diamond Elite MD-9010G weighs 25 lbs.

How Much Weight Is on a Marcy Machine?

A total weight of over 330 pounds is on a Marcy Machine. This includes the barbell, cable weights, and weight plates.

How to Disassemble Marcy Home Gym?

To disassemble a Marcy home gym, follow these steps:

  • Start by removing all weight plates or resistance bands from the machine.
  • Unscrew or detach any bolts or pins securing different components together.
  • Take apart the machine piece by piece, following the assembly manual in reverse order.
  • Use appropriate tools and follow safety precautions.
  • Store the disassembled parts in a safe and organized manner.

Our Verdict on Marcy SM-4903

As great as the Marcy Pro is, it’s not a one-size-fits-all home gym solution because it excludes elite lifters and people above 5’10”.

A better solution for your home gym would be Rogue’s SLML-6 Monster Lite Weight Stack Slinger with a power rack.

The cable-weight pulley is much smoother and offers more weight. Alongside Rogue’s power rack, it offers more durability and safety features than Marcy Pro.

It may be on the pricier side for most users, but it’s worth the investment in the long run.
