The chest expander is a piece of exercise equipment that you may remember the mischievous kids from the "Goonies" movie using to tie up Brand. It is a simple piece of equipment consisting of two handles connected by springs that provide resistance. Using the chest expander is sometimes called strand pulling. Although you would expect the chest expander to target the chest muscles, it can also be used to exercise the legs and back as well.
