Rick McCharles recommends that coaches begin training for Yurchenko (round-off approach) vaults as soon as gymnasts can tumble backward handspring series proficiently.
All gymnasts should do Yurchenko drills at least once a week from that early developmental stage even if the vault will not be competed until years later.
