A:Answer SINGSBASS
This treadmill model is available on the free app, BILT, which will give you 3D steps to follow to make the assembly as easy as possible.
We recommend two people do this assembly together and the average time is about an hour and a half to assemble successfully. The BILT app also will instruct you on needed tools to have on hand, which will include (in this case) an adjustable wrench, phillips screwdriver, and hex key (included).
Let us know if you need any further information by emailing us at ce@ProForm.com.
