"Keep up" is generally used to tell someone to continue doing something that they are doing or to maintain the same pace or level of activity. For example, if someone is walking quickly but you are struggling to keep up, they might say "come on, keep up!" to encourage you to walk faster. Or, if you are studying for a test and someone asks how it's going, you could say "I'm trying to keep up with all the reading." It can also be used as a congratulatory statement, such as "good job, keep up the great work!"
