A balance beam is a narrow, elevated platform used in gymnastics. It is typically about 4 inches wide and can be up to 16 feet long. Gymnasts perform various routines on the beam, showcasing their strength, flexibility, and balance. The beam is often made of wood or synthetic materials and is padded for safety. In competitive gymnastics, the balance beam is one of the key apparatuses, alongside others like the vault, uneven bars, and floor exercise. Athletes are judged on their performance based on difficulty, execution, and artistry. Mastering the balance beam requires extensive training and practice.
