there are a lot of variables to consider.
- How serious are you about training/nutrition/strength and conditioning etc.
- Do you train or plan to train?
- Are you willing to constantly challenge the norm and go beyond to resource new information ideologies training parameters etc?
In my opinion if your not 100% dedicated to the above than studying any tertiary course, for example Human movement, exercise science related degree is not going to be worth while for you due to the cost associated. Also doing a degree part time requires a large amount of discipline and focus on making sure that you are constantly motivated to learn.
As far as just getting the appropriate qualifications go, there are an abundance of companies that offer certifications in personal training. Costs can vary depending on the particular qualification, but in comparison to a university degree, it is the more financially sound option.
But you have to be aware of the risks that you are taking when you actually train a client. For example, you as a trainer aren’t legally allowed to engage a client in focus pad work (boxing pads), your insurance, depending on your provider, wont cover you for injuries sustained to your client during that session.
Also, the courses that these smaller companies offer are usually in the duration of 4-8 weeks and some at 12. The notion that a company can educate a potential trainer about the response to physical activity and the acute and chronic affects is preposterous. As such you will have to constantly prove yourself in the industry to not only increase your client base but also your employability.
This is just the tip of the ice berg, so to speak, when it comes to making the decision about being a trainer.
