“Erica truly is the best of the best when it comes to Prenatal Pilates and Fitness. She is an inspirational woman in so many ways. Often times I see instructors favor the anatomy element over the exercise/physical element, or focus too much on the physical “workout” without proper anatomy and posture awareness…..She has it all going on. She is a living example of a Pilates Pro, working mom, and beautiful woman. I feel lucky to have been able to study with Erica and look forward to learning more.”

Carly Farmer

Erica’s passion is contagious as she shares her industry expertise and go to workout’s. This course is a must for any instructor interested in taking their female clients to the next level. Money well spent!”

“A fantastic course, very thorough and backed by lots of research. This should be a staple course in the fitness industry as it’s more comprehensive, relevant, and beneficial than any other course I’m aware of.”

Personal Trainer

“The content of the Pre-Postnatal Exercise Specialist Course by Erica Ziel has exceeded my expectations. I had not come across any other material on this topic with as much detail and practical applications as this one. I feel completely prepared to work with pre-postnatal women and help them on a much greater level.In my opinion, this must be one of the best pre-post natal courses in the fitness/yoga industry.”
