RockBands are our take on a durable, affordable resistance band for rehabilitation and mobility. Available in five resistances, they include a thorough movement booklet with corrective exercises. Detailed Instructions Included with every RockBand is our new Movement Manifesto, which features a multitude of RockBand-focused corrective mobility exercises and tips. See below for more detail under Added Bonus. Rehab or Exercise Not just for rehabilitation, RockBands make convenient exercise tools for travel, or to scale common bodyweight movements at the gym.
