Most suspension trainers on the market have multiple ways to be anchored and even supply the hardware. If your kit came with a door anchor, wedge it between a partially open door and close until securely latched. You can utilize anchor straps (which wrap around branches or clip onto existing fixtures) for spaces without doors, like studio apartments or outdoor areas. Heavy-duty metal X-mounts are another great option, but should only be secured to load-bearing walls, beams, or overhead studs. Regardless of the mount used, be sure to install the unit with ample space from nearby walls to give you enough room for all planes of motion as you work out. Consult with a professional for the weight-bearing strength of mounting surfaces.
