RE: ACE-certified group fitness instructor
Hi, Georgia! I've been ACE certified in group fitness instruction since February 1997. Much of the textbook for the group fitness instructor exam, especially the core information about exercise physiology, anatomy, kinesiology, nutrition, etc., is a duplicate of the personal trainer exam. I purchased the textbook, study manual, and practice test and studied for it on my own for about 3 months, and passed the test the first try. The test for me was like walking through mud for 3 solid hours, but/so the studying really paid off.
The materials seem expensive, I know, but I believe that the knowledge you gain from them will serve you well for your fitness practice-for-pay AND for your own personal fitness. I still have the Group Fitness Instructor manual AND I have the Personal Trainer Manual textbook, and I constantly refer back to them for refresher information. The more you know for yourself, the less dependent you'll be on fitness hacks that only want to sell you something.
GO FOR THE PERSONAL TRAINER EXAM! GOOD LUCK!
