Attack practice

Attack practice (공격연습, gonggyeok yeonseup) is a kumdo training exercise. In Korean sources it appears as continuous attack practice (연속공격연습, yeonsokgonggyeok yeonseup), abbreviated 연공 (yeongong). One Korean source ties it to the Japanese kakari-geiko (掛かり稽古).

• Who decides the attack: unlike strike practice (타격연습, tagyeok yeonseup), where the instructor creates the opening, here the attacker strikes by their own will.
• The receiver (받아주는 사람, badajuneun saram): should encourage the attacker to come in with confidence, without striking roughly or pushing to intimidate. If an opening appears, the receiver may attack first or counter, as in real practice. The source recommends a ratio of 4:1 to 3:1 and warns that too much attacking reduces the benefit for the lower-ranked trainee.
• Prerequisites: it requires solid skill from prearranged practice (약속대련, yaksokdaeryeon), which includes 연격 (yeongyeok) and 약속연습 (yaksok yeonseup). The instructor should allow it only for those who can already land a single accurate strike.
• Breathing and effort: the Korean federation says that during 연격 or 연공 one should hold the breath for a while, like a 100 m sprinter, and strike with full effort. A forum source recommends doing it in one or two breaths and calls breathing the hardest part.
• Posture: the same forum source warns that chasing speed at the cost of posture only builds bad habits.

In the teaching programs of Korean dojos, continuous attack practice is listed among the basic practices (기본연습, gibon yeonseup), alongside 연격, prearranged practice and the practice of entering and striking.
