In one embodiment, the apparatus comprises a platform which may be used for a variety of applications. The platform comprises an exercise and/or support surface formed by a plurality of modular members which may be interconnected to decrease or infinitely increase the size of the exercise and/or support surface. The exercise machine further comprises first and second utility arms extending from opposite sides of the support platform. Each of the utility arms comprises an upper segment pivotally connected to a lower segment. The upper segment may comprise one or more pulleys and corresponding cables which may be pulled by the person against a selectable resistance provided by a resistance system embedded within the support platform.
