Senior Pilates Reformer

Many seniors find that their balance, flexibility and stamina have diminished over time. A regular Pilates practice can help these issues, and many seniors are amazed at the improvement in core strength and endurance they experience after just a few classes. This class offers an uplifting atmosphere and a warm community while engaging both the mind and body. New participants must have taken the Fundamentals course.


Private Pilates Reformer

Private Pilates Reformer sessions are the best way to exponentially improve your Pilates practice. You can work at a pace other than the one offered in group classes or address specific issues or exercises.

An Important Note About Pilates Reformer Classes: Pilates Reformer classes have an 8 person capacity to allow for personal attention and correction from qualified, experienced instructors. As with any physical activity, please consult your health care provider to ensure that Pilates is right for you. Group exercise classes are appropriate for healthy persons without injury. People with injuries should not participate in group classes without permission from their healthcare provider andinstructor. People with injuries who wish to explore the rehabilitative qualities of the Pilates should begin with private sessions. Participants in classes with injury issues (who are cleared by their healthcare provider) should approach the instructor before class to inform them of their needs or to ask for modifications.

Ultimately, each participant is responsible for their own health and safety within the class. For safety reasons, please plan to come to class at least 5 minutes early. We do not allow participants to join class if they are more than 5 minutes late.
