Go out of both ends. Alternate your lines (F/D/F/D/F etc). On whistle forward takes off with the puck and D without. Both go around set cones and keep their speed. Forward tries to score. D gaps up and defends. Play till completion. Not just one shot or turnover. Play till the whistle. For more content- https://andrewtrimble.substack.com/ or www.aihockeyadvisor.com
