Abstract: Example client management systems and methods are described. In one implementation, a client management system identifies a client of a trainer and determines a scheduling rule associated with the client. The scheduling rule defines a regular schedule for the client's training sessions with the trainer. The client management system receives, from the client, a request to cancel a training session scheduled with the trainer. The client management system reschedules the training session by canceling the training session and scheduling a new training session based on the scheduling rule.
