One of the best home gym systems we’ve tested, the Marcy Pro SM-4903, gives you all the tools you need to build lean muscle, burn fat, and get in great shape without the hassles of travelling to the gym. 

With an all-in-one design, this compact workout station allows you to perform various strength-building exercises simultaneously so you can target multiple muscles groups in a single workout. 

It also has a dedicated landmine attachment for doing pushups, pull-ups, and lunges and a durable cable pulley system for performing high-functioning exercises like dumbbell presses, triceps extensions, biceps curls, shoulder presses, bench dips, and sit-ups. 

Let us look at the features and benefits of this product:

Is Marcy Pro a good brand?

Smith cage:

The Smith cage is the centrepiece of the Marcy Pro SM-4903. The frame is made of heavy-duty steel tubes.

The primary upright posts and the upper and lower bars have a grey, corrosion-resistant paint finish, but the rear bars guide the weight trolleys, and the weight bar stability bars have a chrome finish.

The safety catches, and catch bars on the other side are both coloured red. The catch bars also feature a rubberized coating on top that reduces the noise of a bar drop and prevents the paint from peeling.

The Smith cage is rather big when fully built. It has a footprint of 86′′L x 73′′W (218 x 185 cm) and a height of 85′′. (216 cm). As a result, the machine will not fit in a room with a 7′ ceiling, and you will need at least one foot of space above it to execute proper pull-ups.

Safety elements: 

In terms of safety features, the Marcy SM-4903 cage includes two catch bars, two catch braces, and a Smith machine safety catches. All of these are rated for a weight capacity of 300 lbs (136 kg).

Dual sliding weight trolley:  

Given that the Marcy Pro SM-4903 has a dual sliding weight trolley system, there are many pulley sets on each side. The pulleys are constructed of heavy-duty nylon and include sealed ball bearings for smooth movement.


In terms of accessories, the Marcy SM-4903 has a dip station linked to one of the upright bars. It also has two extended rubberized grips and a 300 lbs (136 kg) weight capacity like most other machine parts.

A pair of two D-handles with rubberized grips is provided for the high and low pulley systems (included). I

n addition, this strength training system lacks a small bar for low rows and a lat bar. Finally, the Olympic 2′′ detachable adapters with spring collars are available for the Smith bar and the weight trolleys.

Assembly and Maintenance: 

You must assemble this Marcy Pro strength training equipment completely. The work will take at least a few hours to complete, but it is not difficult. 

It is best to accomplish this with the assistance of another individual. The accompanying handbook includes step-by-step assembly instructions and diagrams.

You will need a set of Allen wrenches, two adjustable wrenches, and a rubber mallet to complete the construction.

It is recommended to oil the guide rods of the lat attachment and the Smith machine's guide tubes regularly for maintenance. 

There is a bottle of silicone lubricant provided. In addition, you must examine the machine regularly to ensure no broken parts and re-tighten any loose parts.
