I see that your are ACE certified in group fitness. You can manage your CECs and CPR on their website in your account and and re-certify online. It is pretty straightforward.
If you have ACE, yes, they make it very easy for you to recertify on-line. They also keep track of your credits for you. I see you also listed the question under AFAA, so you should contact them directly as well for recertification (you keep track of your own credits with them–or at least you used to have to).
