The DEX II is a forward-rotating, user-controlled inversion machine. The body is placed in a 90/90 position, which helps to flatten the lumbar curve for greater separation of lower vertebrae. Traction is applied to the hip joints and spine, with no loads to the ankles and knee joints. The DEX II is ideal for back extension exercises; it works like a roman chair, but with better ergonomic support – and the unique traction handles offer a method for stretching and increased decompression.
DEX II decompression & extension provides all of the benefits of inversion while holding the user in the 90/90 position, which is the optimum position for decompression. From this position, the user is in a body position relevant to gravity that maximizes muscle performance during back extensions while helping to prevent hyperextension.
