Abstract: The present disclosure provides a resistance band apparatus which overcomes the problems traditionally associated with resistance training—time consuming resistance changes during the same exercise, time consuming adjustments between different exercises, and non-uniform resistance through the exercise motion depending on the height and limb length of the person—by incorporating multiple bands of different resistances into a single apparatus that can be engaged or disengaged from contributing towards the total resistance provided during an exercise, and which can be attached and detached at different points along the length of the apparatus to variations of fixed anchors to provide uniform tension and length for exercise motion. Both the resistances of the different bands and the points along the length of the apparatus at which they are attached are clearly indicated to facilitate easier recording of progress, as well as apparatus setup per exercise for the user.
