I checked catalog for the manual entitled: ACE Group Fitness Instructor Manual 3rd Edition
Thanks for asking! No, it appears that we do not have that title in our collection. Professional manuals and specialized textbooks are often outside our purview as a public library. To find this title in any edition, particularly the 2011 3rd ed., we'd have to seek it through inter-library loan. ILL service comes with a charge for postage, but for titles that are rare or expensive it's often worth trying.
You can pick up an inter-library loan request form at your neighborhood library or place your request directly using the WorldCat database, linked above. Please feel free to call 402-444-4857 with questions!
