Posture Pump® gently decompresses, shapes, & hydrates the discs in your neck & back. When the neck & back lose their natural curved shape, the soft discs that are in between the vertebrae become compressed, & rich lubricating fluid is unable to penetrate & hydrate the discs. This causes premature aging in the form of stiff, dry joints. Posture Pump® counteracts that by lifting, stretching, decompressing, hydrating & shaping the neck & back into its “vital” natural curved shape.
