I find that the instructors are very knowledgeable so they correct my form often and know how to spot errors. Related to this, because the instructors focus on proper form and good technique, I like that we are given modifications and different options for exercises so we can be sure we're performing them properly and without hurting ourselves. I have taken pilates before with not-so-qualified instructors and found that a lot of detail - especially knowing which muscles to work with - gets lost. I have found that at Studio Zee I have been able to really understand what the core principles of pilates are rather than just doing a bunch of fast crunches and wobbly leg lifts. The added benefit is that my ballet technique and swimming technique have improved, too!
There are many things I like about studio zee. I like the small class size, that you sign up online to reserve your spot so that you don't have to rush for a spot. The price is amazing for someone knew to Pilates and very reasonable for returning customers.
Prompt replies to my queries, emails, etc. Lovely studios with all types of Stott equipment. And above all my teacher, Alisun, the consummate professional who knows how to tailor my private classes to my specific (and usually variable) needs. I've said all this before but it bears repeating.
Small class sizes with excellent instructors. I never feel as though I'm going to hurt myself or do something incorrectly, the instructors are always correcting or offering modifications. I love the variety of classes too:-)
