Pick the location where you want to mount the supports. Choose a location away from doors or other high traffic areas that can interrupt workouts or lead to injury.
Climb the ladder and locate the ceiling joist or truss. A truss is the frame beam extending up in a triangle on raised or open ceilings. A joist is a cross beam extending across to support ceiling panels and attic weight. Locate the beam by tapping on the ceiling until you hear a solid sound rather than a hollow sound.
Measure the spot where the mount will go, marking bolt holes with a pencil. If you are using two mounts, set them approximately shoulder width apart. Measure and mark the holes.
Drill the bolt holes into the beam. Most mounts have two to four bolt holes.
Bolt each mount in place, tightening the bolts with a wrench. Pull on the mount to make sure it is secure.
Attach a ring to the mount to hold the resistance band.
