Abstract
The application discloses a roller assembly that utilizes internal resistance components to increase resistance to enhance training intensity. The internal resistance components include a rotatable resistance component or impeller coupled to an outer tubular body of the roller. Embodiments disclosed also include a second resistance component to restrict rotation of the rotatable resistance component increasing the torque required to rotate the outer tubular body. In an illustrative embodiment, the rotatable resistance component forms an impeller which is disposed in a fluid chamber within the tubular body and the second resistance component is disposed in the fluid chamber and maintained in a stationary position to impart resistance to rotation, thus increasing the torque required to rotate the outer tubular body.
