Quick answer: a punch is a sharp motion in which one or both arms drive straight out from the body, fist leading, similar to a boxing punch - used to add a strong, percussive accent to a chant or dance.
What Does It Look Like?
Starting from a bent position near the body, the arm extends sharply straight out, fist leading, stopping with a snap rather than continuing into a wider motion - the emphasis is on speed and sharpness rather than a held, extended shape.
How the Term Is Used
"Punch" describes this specific driving, percussive motion, and is often used to describe the quality of a motion generally - a "punchy" motion is one performed with sharp, forceful energy.
Where It Fits in a Routine
Punches commonly appear as an accent motion on a strong musical beat, often within a chant, and can be performed with one arm or both depending on the choreography.
What Judges Look For
Judges are generally looking for a sharp, fully extended finish, matching arm angle and speed across the team, and clean, precise timing.
Related Motions
Punches are often used alongside other sharp, accented motions like daggers, and typically return to a neutral position like clean between accents.
