About Us

Our Mission

Rhythmic Gymnastics is an Olympic Sport that eloquently combines the beauty and grace of dance with the agility and dexterity of gymnastics. Rhythmic gymnasts use hand apparatus such as RIBBON, ROPE, HOOP, BALL, and CLUBS that are constantly in motion, synchronized with their body movements and beautiful music.

Our program accommodates all levels and ages, from 3 year old to advanced competitive levels. Our training philosophy is to develop gymnasts at every level from the beginning, developing skills for general movement education, health and for participation in the competitive program. Rhythmic Gymnastics is a unique sport for girls, which promotes developing coordination, poise, grace and confidence.

Rhythmix gymnasts come from Chicago north suburbs, including Buffalo Grove, Mundelein, Highland Park, Vernon Hills, Libertyville, Wheeling, Lake Zurich, Deerfield, Lake Forest and Lincolnshire

Although fascinating to watch, there is more to Rhythmic Gymnastics than meets the eye. Rhythmic builds physical abilities for STRENGTH, POWER, FLEXIBILITY, AGILITY, DEXTERITY, and ENDURANCE. The sport also enhances MUSICAL ABILITY OF HARMONY and RHYTHM. In addition to establishing lifelong patterns of physical activity, which promote health and fitness, it also requires discipline, develops courage, and builds self-confidence - the qualities all transferable to other areas of life. Gymnasts learn to control their bodies and sharpen their minds. Rhythmic also encourages creativity while allowing the gymnast to express herself in a unique and individualized way.
