You will find that the Health Shack centre is a welcoming and relaxing environment in which to exercise. It is not a gym inhabited by individuals displaying their athletic prowess! You can exercise at your own pace and capabilities, and socialise and meet new friends. There will also be a number of private sessions reserved for groups with similar exercise requirements.
You do not need special clothing or footware. Just ensure you wear comfortable clothing that will not restrict movement of your body as the machines manipulate the various muscle groups.
