Age-appropriate actions include spinal activation and cross-lateral movements that are important for a child’s brain and body. The pacing of these unique, motivating fitness routines is simple, repetitive, and easy-to-follow. Catchy tunes and fun sound effects are sure to encourage kids 4-7 to want to move, wiggle and jiggle! Younger children will also be eager to jump into all the fun, gaining valuable brain-based benefits for their own developmental stage.
