Do you have a personal trainer or group exercise certification through an organization like NSCA, AFAA, ACE, ACSM or AEA? While you're still a student courses related to your certification can count toward your recertification. After graduation, attending a fitness conference is the best way to maintain your certification. The ECA World Fitness conference is Nov 9-12 in Ft. Lauderdale, FL.
If your employer requires you to be certified, you may have access to some professional development funds that would help lower your cost to attend the conference. Also coming up this summer are:
IDEA World Fitness Convention, July 5-8, San Diego, CA
DCAC, Washington, DC, Aug 2-5
