Exercise device and method

An exercise device comprising:

• a flexible band formed in a closed loop, a section of the loop having a plurality of band layers in use and in tension, each of the band layers overlapping each other, the section of the loop having a first end and a second end, a remainder of the loop extending from the first end, away from the section of the loop, and being connected to the second end, to form the closed loop;
• and
• at least one tension adjuster associated with the band for selectively adjusting the tension of the loop, the at least one tension adjuster comprising a first selectively actuatable adjustable element positioned on the flexible band and configured to move along the flexible band, the section of the loop having the plurality of band layers extending between the first selectively actuatable adjustable element and a second selectively actuatable adjustable element positioned on the flexible band, the at least one tension adjuster being configured to increase tension by moving the first selectively actuatable adjustable element to increase a length of the section of the loop having the plurality of band layers, and to decrease tension by moving the first selectively actuatable adjustable element to decrease the length of the section of the loop having the plurality of band layers, wherein the first selectively actuatable adjustable element is configured to expand and contract the proportion of the closed loop having the plurality of band layers relative to the remainder of the loop.
