I’ve been a successful personal strength trainer for many years and would like a certification.
When I was looking at certifications I saw a slew of different options online. I went to the gym and then had a conversation with them and chose the ISSA. While I would not say this is the fastest method I will say it is a recognized certification accepted by such large gyms like Golds, L.A. Fitness etc. I will also say it is very thorough.
There are certifications available where you take a 140 question multiple choice exam online which seems like the fastest way. The ISSA exam is 100 plus multiple choice questions, then there’s at least 20 true and false, approximately another 10 matching, then you have to write 6 essays, and then there is the practical questions section. This section has you calculate out caloric diets, calculate BMR’s, write a nutritional/supplemental programs. Then there are two scenarios where you have to write a training program in detail. So this would not be the fastest way but rest assured you will not pass this exam unless you truly have the necessary knowledge it requires to be a personal trainer.
