01Front punch
The straight line
The tight arc
05Side-view medium-wide shot of a lean Mexican boxer in a grey hoodie throwing a single left hook into a heavy leather bag in a dim, gritty gym, photoreal, slow motion, locked camera. 0–2s: he sets his stance close to the bag, hands high. 2–4s: his lead hip and shoulder rotate together as his left arm swings in a tight horizontal arc, elbow bent at ninety degrees. 4–6s: the fist lands on the side of the bag, which buckles and swings away, dust lifting off the leather. 6–8s: his arm returns to guard as the bag sways back. Throughout: one hard work light overhead, chalk dust hanging in the air, full body visible, fixed camera.
Give the arm a shape. “Elbow bent at ninety degrees” stops the hook from becoming a wide, swinging slap.
