An exercise machine comprises a frame, a resistance element to provide resistance for performing exercise, a pair of arm assemblies connected to said resistance element and pivotally mounted to the frame so as to be rotatable about respective first axes to perform exercise and respective second axes to adjust the travel path of the arm assemblies. Moveable pulleys with at least two axes of rotation connect resistance to the arm assemblies. The moveable pulleys rotate and align when travel path adjustments are made to the arm assemblies and during exercise. The moveable pulleys also bumper against guide pulley assemblies to provide the arm assemblies a rest position. The rotation of the moveable pulleys allows the connection assembly connecting the resistance element to the arm assemblies to maintain a substantially constant tension when travel path adjustments are made.
