Peanut rollers create a channel for the spine. Single rollers provide a broad, uniform surface. Each design suits different applications and body areas. Equipment helps, but movement matters most: Start your 14-day free trial Peanut Roller Two balls connected or shaped roller creating a channel. Allows rolling alongside the spine without direct vertebral pressure. How It Works The peanut shape creates a groove that accommodates the spine while pressure applies to paraspinal muscles. This allows upper back and spine area work without rolling directly on vertebrae. The dual-point contact targets muscles on both sides simultaneously. Best For Thoracic spine area Paraspinal muscle work Avoiding direct spine pressure Upper back work Symmetrical bilateral pressure When to Avoid For large flat muscle groups When broad coverage is needed If channel does not fit your anatomy For general full-body use Example Exercises JME 150 Sitting in your chair, rotate your upper body both left and right. Don't do this too fast - find what works for you. JME 154 Either sitting or standing at your desk, extend your upper body toward the direction behind you - either putting your arms above your head or keeping them at your side. Single Foam Roller Traditional cylindrical roller with uniform surface. Versatile tool for general self-massage. How It Works Single rollers provide broad, uniform pressure across whatever contacts them. The versatile design works on any body part. Various densities and sizes suit different needs and areas. Best For General full-body use Legs and large muscles Versatile applications Broad pressure distribution Universal self-massage When to Avoid For spine-specific work needing vertebral clearance When targeted bilateral pressure is needed If broad pressure is too diffuse Example Exercises JME 94 Slowly bend forward and reach your hands toward the floor. JME 113 Place one knee on your chair and move that knee both forward and back to feel a stretch in the front of your leg. The Verdict Peanut rollers excel at spine-adjacent work with vertebral clearance. Single rollers excel at versatile, general-purpose rolling. Use peanut design for thoracic spine and paraspinal work. Use single rollers for legs, hips, and general use. Having both provides complete rolling options. Movement Matters Most Equipment can enhance your practice, but consistent movement matters more than any tool. simplmobility provides joint-specific routines in 2-3 minute sessions that work with or without equipment.
