Teeter Hang Ups EZ-UpTM Inversion System includes an Inversion Rack with Gravity Boots. Designed for the fit and flexible user, the Inversion System provides a safe and convenient method of full inversion. The dual bar system is designed for easier mounting and dismounting, and allows you to hang free from the door frame for maximum range of motion.
The EZ-UpTM Inversion System offers a full body stretch and is a great tool for inverted exercises (like crunches, sit-ups and squats). In fact, full range inverted sit-ups are ten times tougher than horizontal sit-ups, with minimal load on the back.
