In basketball, 17s is a conditioning drill where players run from sideline to sideline 17 times in just over a minute. The drill can be modified in various ways, such as dribbling, defensive sliding, or running forward/backward. The last run (17th) is usually done as fast as possible. The drill is designed to improve endurance and speed, and it is commonly used in basketball training programs to enhance players cardiovascular condition. The name "17s" comes from the 17 times players must run to and from the sides of the court for a minute. The drill is considered challenging and effective for improving players mental and physical prowess.
