For group fitness:
For Pilates
Offer a work study deal and the twins who run the program have beautiful posture especially the legs(very dancer based) and their training was origionally stott training.
One of the cheaper certs.
Call them, they sometimes offer free pilates certs.
They also offer free pilates certification in exchange for work hrs.
Awesome certification but expensive.
For Yoga
You are in training for 3 intense months.
The main site for all of the yoga studios/programs.
Seems quite intense!
Very doable for every level...more for the group fitness instructor teaching a fitness based general yoga program.
