Famous in Chinese sports memory through 程菲 (Cheng Fei), the gymnast who pioneered the 'Cheng' vault (a roundoff-back-handspring with full twist) and won Olympic gold on the apparatus in 2008. 跳马 is one of the marquee Chinese gymnastics events.
memory
Literally 'jump horse' — the apparatus was historically a wooden 'horse' the gymnast vaulted over. Modern competition has replaced it with a curved 'tongue' table, but the name 跳马 stuck. Don't confuse with 木马 (mùmǎ, 'wooden horse / Trojan horse').
