摘要：An exercise apparatus including a base structure comprising a fixed lower body exercise platform and a pair of elongated upper body exercising units is disclosed. The units are mounted to the base structure by mounting structure that enables the units to be moved by a user against a yielding resistance in any direction with respect to a center in conjunction with the user stepping onto or off of the platform in any direction while performing an exercise thereon. The elongated upper body exercising units preferably include two telescoping exercise poles to be grasped by opposite hands of the user and capable of both oscillating and reciprocating upper body exercising motion. A variable volume air chamber is defined in an annular gap between coaxially arranged inner and outer members of the telescoping exercise poles and a restricted air passage communicates with the air chamber. Reciprocating motion of the telescoping pole causes the volume of the air chamber to alternately expand and contract and the restricted air passage restricts air flow into and out of the chamber to effect a resistance to the reciprocating motion. The poles are preferably mounted to the base structure by coupling each pole to a separate pivoting arm that is secured to the base structure so as to be pivotable about a vertical axis. Lateral orientation of the poles with respect to the
base structure and each other can be varied by pivoting each pivoting arm to which each pole is attach
ed and then securing each arm in a desired orientation.
