Drills by Size
All of the drills on the site indicate the size of the drill through the means of an icon that communicates the minimum amount of players required to perform the drill. This is mostly determined by the number of players that it takes to complete one entire repetition of the drill.
Each drill can handle more players than the size icon indicates. The icon is purely meant to show the minimum amount of players required. For example, if a drill is marked as an individual drill, then it is certainly possible to set up the drill to have multiple individuals take turns rotating through the drill or even to have multiple individuals spread out and all perform the drill at the same time.
