Warm up young players through play: move across the channel as different animals to mobilise the whole body and build coordination.
Mark a short channel, about 20 yards, with cones at each end. Call out an animal for each length and the children move that way down to the far cones: bear crawl on hands and feet, crab walk with the tummy up, frog jumps, tall giraffe walk on tiptoes, then scamper back like a mouse. Keep it playful and quick, and let them suggest animals too. No ball needed.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
