The basic workout would be 3 sets of 12 for each exercise but it’s more important to understand that if you want to build muscle or strength your sets need to be at least somewhat difficult to force muscular adaptation. So think about what you want to achieve and if it’s really easy you’re probably going nowhere.
Just because this is a beginner workout it doesn’t mean it isn’t very effective. These are fundamental exercises and you never get too good for the fundamentals.
