Onsight's Crushers Club is designed for those older children with some climbing experience who are eager to learn more about the sport and how to improve their skills. Club members will climb, train, and receive coaching in a non-competitive, supportive, and encouraging environment. We have developed a program that allows for personal growth and development while fostering respect, communication, and character building. Through both personalized coaching and group-based instruction, we work with motivated young adults to improve strength, refine movement techniques, and teach them the mental aspect of climbing. Club members are encouraged to participate in competitions, but are not required. Club members who are 13 and over will be taught how to belay if desired. Crushers Club is recommended for those between 11-14 years of age, but younger children with climbing experience may be invited by one of our coaches to join.
