Taking a private class does cost more than a group class. The benefits to you are having one on one to help with finding the right balance between comfort and correct posture in the pose. We are individuals, so each of us has a different skeletal and muscle set up. This could be from and injury or how you use your body or just how you are put together.
Without going into all my education, my specialty is taking you when your classes are set up. Having more than one plan. Each day bring a new set of needs to your body.
I look forward to talking to you about Yoga and Pilates.
