One hour private sessions are the best way to get started if you want or need a truly personalised approach.
Within a couple of sessions your instructor can create personalised written programs for use in and outside of your instructor led interactive online sessions. 

Semi private sessions allow you to share your instructor with just one, two or a max of three other clients. You will still have a personalised program and the small numbers allow for more individual attention. The most cost effective access to personalised clinical attention from your instructors.

Mat Pilates is designed for healthy bodies that do not need so much individual attention.  Clients perform the same exercises under the skilled direction & sharp eyes of the instructor, who corrects technique & posture whilst also  providing cues, encouragement & exercise variations.
