Practice floorball stick handling from different postions. The pattern or boxes in the pictures can for example be taped on the floor. If the different positions are visual, then it’s also easier to practice the drills in different positions and the players will easier understand the advices and directions from the floorball coach. You can perform the stickhandling practices in front, diagonally in front, forehand / normally, and on backhand. The stickhandling drills will also work great as homework during the floorball off-season.
