Is this commercial quality or residential quality?

Our products are 100% commercial grade and are in use in many boutique commercial gyms across the US. By making combo machines and sticking to the steel, we keep the cost low and make it affordable for residential users.

Can I add additional weight to the machine?

No, our machines are at maximum but you can add accessories to increase weight or resistance.

How do I maintain this machine?

Our machines need very little maintenance. We recommend white lithium grease to lubricate the moving parts on an as needed basis (based on usage). Once per year we recommend re-tightening all the bolts to prevent unnecessary wear & tear.

Arrives in one box. Includes all parts for full assembly; frame, pads, weight plates, pins, hardware & instruction manual.

SFE machines are heavy-duty, commercial-grade equipment designed for serious training, and they require proper tools and at least two people for assembly.

They arrive in wooden crate on a pallet. Our machines are built for heavy duty use and demand time and effort to set up correctly. We provide detailed assembly manuals for every model, but please be prepared for the process.

Although the majority of our customers are able to assemble the machines themselves, if you are not experienced with equipment that involves bearings, guide rods, weight stacks, and/or heavy frames, we strongly recommend hiring a local fitness equipment technician.

Companies such as Fitness Machine Technicians typically charge $200 to $400 per machine, which can save you 2 to 6+ hours, depending on your tools and experience.

Please note that we do not offer assembly services outside of the Phoenix metro area, as hiring locally is usually faster and more cost-effective, and we prefer to pass those savings on to you!
