Slip and counter

The prompt

Coach's point-of-view handheld shot in a crowded boxing gym, a Puerto Rican boxer in a white tank top slips the coach's slow mitt swing and counters into the other mitt, cinematic, real time. 0–2s: he bounces in his guard, eyes on the lens, the coach's mitts visible at the frame edges. 2–4s: the left mitt swings across the frame at his head; he bends at the knees and dips under it to the outside. 4–6s: he rises and fires one right cross into the right mitt just in front of the lens, the camera jolting. 6–8s: he resets his guard and nods, light on his feet. Throughout: the boxer visible from head to waist, hanging bags and ring lights blurred behind, warm tungsten light, sweat glistening.
