Abstract
Lunge poles used to assist a user in maintaining his or her balance while performing lunges include a base, a pair of resilient couplings mounted on the base and a pair of tubular poles extending from the resilient couplings. The base is generally planar and includes four outwardly extending feet having rubber pads on the bottom thereof to frictionally retain the base in position on a floor. A pair of holes is formed in the top of the base for receiving the resilient couplings. An annular groove is formed in the couplings for snap-fitting the couplings with the holes of the base. The couplings include an elongated tapered stem which extends downwardly into the base and a criss-crossed shaped top portion for receiving a bottom end of the tubular poles. A middle section of the couplings is tapered downwardly forming a thin neck which allows the couplings to pivot on the base in a 360.degree. range of motion. A large circular flange is formed on the couplings to prevent the resilient couplings from being pushed through the holes of the base. Each pole includes an upper section which engages a lower section. A foam handle is disposed around a top end of the upper section of each pole. …
