I think that it depends on your personal situation. If you want to complete your personal training course and get the certification you need to spend a lot of time on that. Some people using do my assignment services like https://au.papersowl.com/do-my-assignment or any other service like this one. You need to pass exams and show your experience on this subject. Fitness exams are not that simple but I think that everyone who uses assignment services could do that. At least I think so. I would recommend you to watch some videos on YouTube and read more on this forum. This would give you enough information about the training course. And don’t forget that your study depends on the certification you are studying for. This is an important thing.
