An exercise apparatus for supporting a range of resistance exercises, including exercises for providing bi-directional resistance to both the upper and lower body over a wide range of positions is disclosed. The exercise apparatus includes a base having a platform disposed thereon. An at least one elongated member is pivotally attached at its proximal end to each of the first and second ends of the base, and disposed in opposing relationship to form an at least one pair of opposing elongated members. An open loop resistance assembly is associated with each of the at least one pair of opposing elongated members. The resistance assembly functions to provide resistance against the direction of force applied by the user.
