1. A method of providing visual feedback to a user of an exercise machine including a transparent fluid tank configured to provide a fluid-based resistance force during operation of the exercise machine, the method comprising:
providing a rowing machine having a frame coupled with a seat and a fluid container, the fluid container having a fluid displacement device positioned therein coupled with a drive cord that is configured to be pulled by the user when seated, the rowing machine configured so that the user sitting on the seat faces the fluid container when pulling the drive cord,
the fluid displacement device being configured to displace the fluid in the fluid container by rotating the fluid in the fluid container in response to a force exerted by the user,
the fluid container being coupled with an illumination housing having face with a recess and a plurality of light sources positioned in the recess, the illumination housing positioned relative to the fluid container to direct light into the fluid tank, the illumination housing being positioned outside of the fluid container and being centrally located with respect to the fluid tank;
directing light into the fluid tank from the plurality of light sources positioned adjacent to the fluid tank to illuminate a fluid inside the fluid tank such that the light is scattered by the fluid and made visible to the user positioned on the seat while pulling the drive cord;
controlling a quality of the light directed into the fluid tank based on a parameter; and
adjusting the quality of the light based on the parameter.
