A user-operated exercise apparatus having a resistance member to provide a variable resistance force to exercise input from the user, wherein the resistance member comprises at least one turbine (1 ), a fluid flow circuit (2) having an inlet to the turbine and an outlet from the turbine, and at least one pump (3) the turbine being a bi-directional impeller arranged to create the resistance force of the resistance member when driven in one direction and an assistive force to assist the exercise when driven in the other direction. The apparatus may be a cycle trainer e having at least one front wheel and at least one driven rear wheel, the resistance member to be engaged by the driven rear wheel to provide the option of assistive or resistive rotational force in order to reproduce the forces encountered in a cycle ride. |
