Frequently Asked Questions
Do you offer financing?
Financing is available for qualified purchases on larger orders. Ask about it when you request your quote so it can factor into which condition tier and how much equipment you go with.
Does picking it up myself affect the warranty?
Yes — equipment you pick up from our warehouse yourself carries no warranty, regardless of condition tier. By taking pickup you're confirming you inspected it and accepted it in its current condition. Warranty coverage applies only to equipment we deliver. See our Terms and Conditions for the full policy.
Do you sell new equipment, or only pre-owned?
Both. Pre-owned is our focus and where the value is, but we sell new equipment when it makes sense — when it fits the budget better, when a specific piece isn't in used inventory, or to fill the gap in a package or circuit so the floor ships complete. We're also the exclusive gym80 dealer for Texas, Arizona, New Mexico, Arkansas, Louisiana, Mississippi, Alabama and Colorado — a German commercial strength line we sell new. One quote can mix new and pre-owned.
Can you install it, not just deliver it?
For commercial jobs, yes — our sister company Fit Supply's install teams handle that nationally. Ask when you request your quote and we'll get you connected.
Who services the equipment after I buy it?
Our sister company On Site Fitness Service runs dedicated repair and preventive-maintenance programs. Ask about a service plan when you request your quote, especially for a space nobody is watching day to day.
Can I visit the warehouse and shop in person?
Yes — the warehouse at DFW Airport is open to the public, Monday–Friday 9:00am–5:00pm CST, with weekend visits by appointment. Walk the floor, put your hands on the exact machines you found online, and get honest answers in person. Retail buyers are welcome, not just facilities — plenty of garage gyms and luxury home gyms start with a warehouse visit.
