To improve spinal curvature, you are required to change out the density and diameter of rolls progressively, which is why we sell foam roller sets at a discounted price. Additionally, if you sustain injuries or are sore from training, you need softer and smaller diameter rolls for short periods before using harder and larger ones. Finally, a professional athlete would especially benefit from owning a complete set of rolls to utilize as needed.
Restoring proper spinal curvature requires foam rollers adequately sized to support the current neck and low back curves to lie over after performing the back twist exercise. Depending on existing injuries, pain, and shape of your spine, different diameters and densities are required for molding your spinal column into a more desirable form. We provide foam rolls in five different diameters and three different densities for the neck and low back. There are thirty (30) neck and back shaper rolls and two (2) Back Trac foam rolls.
