The Lifegear inversion table is a piece of fitness equipment that enables users to safely position their bodies to go upside down, thereby reversing the effects of gravity on joints and the spine. While the Lifegear company is no longer in business, Lifegear inversion tables were popular because of their simple design and economy, and are still in many homes. Instruction manuals and parts for certain models may be purchased online (see Resources).
The design of the frame is a simple A-frame which can be opened and locked into place with the horizontal spreader arms. Make sure that the horizontal crossbar is facing forward, indicating the front of the frame. The side handles can be attached at the apex of each side and bolted into place.
The table bed consists of a padded rectangular platform. Turn the padded platform over, so that the padded side is facing the floor and the back of the platform is exposed to assemble the support beams. Attach the support beam by inserting the top section into the holes at the top corner of the table bed. Properly align the connections to the holes and firmly push until it clicks to lock. The side arms can be similarly aligned to the corresponding holes and pushed until locked. Two center bolts can be tightened using an Allen wrench.
Roller hinges allow the inversion table to rotate within the A-frame. Locate the pivot pins along the side of the center support beam at the back of the padded platform. The pivot pins appear as protruding bolts connected to a metal bar with holes. For each side, attach the locking mechanism to the last hole and push the side lever to lock.
Attach the padded platform to the A-frame by holding the padded side forward (i.e., in front of the horizontal crossbar). Locate the center hole at the apex of each side frame. Insert the pivot pin on one side of the platform into the corresponding center hole and repeat on the other side. The pivot pin will be covered by a guide when it is properly locked into place.
The height bar contains the ankle rests and foot bar, which can be adjusted according to the user's height. The height bar is designed to rest against the crossbar to prevent over-rotation when facing forward. The orientation of the height bar should have the rollers facing down and the slots on the bar facing forward. The bar can be inserted into the bottom of the support beam when the locking pin (at the base of the support beam) is pulled out. When released, the locking pin slides into one of the slots to secure the position. Make sure the bar is locked into place by firmly pushing and pulling the bar and checking that the bar does not slide. Adjust the height bar so that the foot bars lie comfortably on top of your feet and the ankle rests are in front of your ankles to prevent slipping when inverted.
