Abstract: A muscle support garment and method for applying compressive forces to muscles within a treatment area are disclosed. A band of stretchable wrap material is secured to the garment and is wound in an overlapping spiral manner on the inside of the garment, encircling the treatment area. The band of wrap material is longitudinally adjustable to vary its tension and the compressive forces applied, from external of the garment. Overlapping loop retainer structures secured inside the garment slidably entrain and retain the wrap material in an overlapping manner. The garment may include an inner liner.
