An exercise apparatus may include an elongated tube disposed between a pair of handles. The elongated tube may be stretchable and flexible, making the exercise apparatus ideal for use in resistance training, amongst other sports and activities. The elongated tube may be attached to each handle by a grommet, a gasket, and an insert. An end of the elongated tube may be threaded through the gasket and may receive the insert, which prevents the end of the elongated tube from retreating back through the gasket. The grommet may be arranged on the gasket and affixed to a strap defining a portion of the handle.
