A combined exerciser and physical fitness performance monitoring apparatus and related methods. The apparatus includes at least one fluid working device, such as a pneumatic ram, which serves to provide an adjustable load. The fluid working device is movable using an adjustable mount to vary the compression ratio and loading rate. The fluid working device is connected to a user interface, such as foot pedals or hand holds, using a connection linkage. The apparatus also preferably includes a load modifier which adjustably engages the connection linkage and allows the rate of mechanical loading to be varied. This construction allows a large range of loads and force rates to be achieved.
