I’ve been a successful personal strength trainer for many years and would like a certification.
I agree with Karin as well. Many gyms will look at who you are certified through and she has listed the top certifications they look for. I took the ACE exam just a few years back – it was tough but not impossible. I had a full time job at the time and dating my now husband and it took some time. Overall the material is very thorough and they cover many topics.
