Resistance Band Exercises (Lower Body) To begin with‚ the following resistance band exercises should be performed approximately 1 - 3 times per week. Ideally they should not be performed on consecutive days‚ to allow muscle recovery. As the strength improves‚ the resistance band exercises can be progressed by gradually increasing the repetitions‚ number of sets or resistance of the exercises provided they do not cause or increase pain. Hip Extension Start this resistance band exercise at side of the
