PDUs, or Professional Development Units, are earned through professional development activities such as attending webinars, taking courses, or contributing to the profession by mentoring or creating content. You need to spend required hours to earn equivalent PDUs ie one hour project management seminar would earn you 1 PDU.
There are two main types of PDUs: Education PDUs and Giving Back PDUs. Education PDUs are earned by participating in educational activities, such as taking courses, attending workshops, or reading books. Giving Back PDUs are earned by volunteering your time to the project management profession, such as speaking at conferences or mentoring other project managers.

A simple way to earn PDUs is to enroll in a course that offers PDUs. This way you do not have to track and worry about the TOTAL PDUs and PMI talent training requirements. Plus you will learn the new required topics as well.
The other ways to gain PDUs are to volunteer, read, and present. The downside is that you may need to track the PDU requirements yourself.
