Does the machine require assembly upon delivery?
Commercial strength equipment of this size typically requires some on-site assembly and setup. We recommend contacting us at service@omahasportsandgames.com to discuss delivery options and whether professional installation services are available in your area.
How is this machine shipped?

What is the difference between the Dual Biceps Curl / Triceps Extension and buying two separate machines?
The dual machine combines both functions in a single compact footprint, saving floor space and cost compared to purchasing two individual units. It is ideal for facilities that want efficient circuit training flow and need to maximize their square footage. For very high-volume gyms that require simultaneous use of both stations, separate machines may be a better fit.
