The most versatile of the Flex Technology Series, the Teeter Hang Ups EP-550 Sport offers more than just back pain relief with additional features ideal for stretching and strengthening. EZ-Stretch Traction Handles, one of Teeter's most popular accessories, add decompression and movement options in partial inversion. And the included EZ-Up Gravity Boots, with super-soft foam surrounded by a flexible, highly durable shell, offer even greater comfort during fully inverted exercises. Work your core, leg and glutes on your Teeter inversion table or even at the gym! Competitors have tried to mimic our best-selling products, but looks are where the similarities end. The real Teeter Difference is found in our premium components and innovative design born from 30 years of engineering evolution. Teeter inversion tables meet UL (Underwriters Laboratories) voluntary and stringent inversion table safety standards, and our inversion tables consistently outperform the competition in testing.
