Finish under fatigue. Do the work first, then take a composed touch and a clean strike with tired legs, holding the technique and hitting the target when it is hard.
The striker sprints out to a cone and back to raise the heart rate, then immediately receives a feed at the edge of the box and finishes. Emphasise holding the technique and composure with tired legs. Vary the work and the service. Keep the recovery short so the finish is genuinely fatigued. Rotate the striker and server.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
