Exercise machines having a user support and at least one user engagement actuator assembly wherein motion of the at least one user engagement actuator assemblies is resisted in both the push and pull directions by the resisted rotation of a one-direction flywheel that is operatively engaged with a braking mechanism. The resistance of the push direction can be less, greater, or equal to the resistance of the pull direction. Each user engagement actuator assembly can be configured to create various unique push and pull exercise stations. Multiple exercise stations can be mounted on each machine that can be operated independently or concurrently.
