Hello, and welcome!


Pilates Encyclopedia was created by me, Mara Sievers, NCPT, out of the desire to gather everything I’ve learned about Pilates in one place for easy reference. I had gathered copious amounts of information, exercises, and cues over the years, but it was spread all over the depths of my computer as well as several notebooks, loose pieces of paper, and sticky notes. Some gems of knowledge might be forever lost in the grey matter labyrinth of my mind.

If I only had all that knowledge available in one place!

The world wide web is awesome. And there is incredible wisdom scattered all over it. But that’s just it. Don't you find it tedious to spend hours sifting through Google search results in an effort to find the one piece of information you're looking for? Furthermore, can you trust the source of the article? Who wrote it? Does this person work with clients day in and day out? Over and over again, I was frustrated that I spent hours at the computer (not my favorite thing in the world) and still didn’t end up with the answer I was looking for.

Nowadays, the edges of what is Pilates and what isn’t are starting to blur. Many Pilates instructors are also certified in other modalities, such as various forms of exercise or body work, i.e. yoga teachers, massage therapists, physical therapists, personal trainers and much more. We all want to help our clients to move better and feel better in their bodies. We use whatever tools we have available. I think that’s great. But if we mix everything together, then my head starts spinning.

This doesn’t mean I consider myself a classical instructor. As with spirituality, my foremost desire is to gather as much knowledge from as many sources as I can, question everything, and gain my own insight. I’m incredibly curious and skeptical enough not to take everything at face value. Like a three-year-old - I want to know why. It’s my favorite word.

Out of this curiosity and desire to dig deeper, I started to research any and all styles of Pilates. Some things resonate more than others. That doesn't mean they're less valuable. I think we all have something to share. As we all know from our experience with Pilates, no two bodies are the same, no two minds are the same. I find it fascinating to compare different versions of the same exercise, and understand why I would choose one over the other, and who would be the appropriate person to try it with. The huge variety of exercises, variations and cues ensures that Pilates can serve everyone, and it will never get boring.

Breaking down the exercises is hugely beneficial to me!

"Thinking about each exercise in more depth deepens my understanding. On top of that, it's so lovely to feel welcomed to ask questions."

I have such a huge appreciation for the Pilates Encyclopedia!

"Being a teacher-in-training, I feel like it's essential to have access to this information. There are so many times I need an answer to a teaching question and the Pilates Encyclopedia tells me the information I need very simply and clearly!"

A brilliant resource!

"As a teacher, it's great to be reminded to come back to intention, intuition, finding space and flow as opposed to forcing clinical execution of form, which doesn't feel as great. Thanks for working hard to make this."

More Success Stories

Finally, even though I strive to gather all my knowledge here, it can’t be comprehensive or all-inclusive. This site started out with just one person, and there are many many many Pilates movers out there who have experienced Pilates differently in their own body-minds, as well as in their students’.

Hence, this is a work in progress that will grow as we learn from each other, and it will remain eternally and blissfully incomplete.

If you have something to share, I invite you to contribute to this site. Send your articles to [email protected].

I also encourage you to please send me your questions. I answer all of them.
