An exchange or dual-exchange in boxing occurs when two boxers trade punches. This often leads to simultaneous hits, and subsequently the boxer with greater strength and/or endurance gains the upper hand. Occasionally, however, one or both of the boxers will dodge or parry the other's punch.
In Hajime no Ippo, when two boxers exchange punches repeatedly:
- If their punches hit it becomes a slugfest. The boxer with more punching power, endurance, and/or fighting spirit will eventually win.
- If their punches miss it becomes a high-level exchange. The boxer with greater technique
will eventually hit.
