The present invention provides an exercise equipment in which an exercise room unit and two side tanks can be compactly arranged in a small installation space, and which can walk underwater, take a bath, and shower. The exercise room unit (2) includes side tanks (3) and (4) that are arranged in contact with both sides of the exercise room unit (2) and that can store water or hot water to be supplied to or returned from the exercise room unit (2). . The side tank (3) has a double structure having an intermediate water storage tank (27) between the inner member (25) and the outer member (26), and is connected to the upper part of the outer member (26). ), A lower pipe (21b) connected to the bottom of the inner member (25) for supplying or draining water to the inner member (25), and an inner member (25). A check valve (28) provided at a predetermined height and allowing only the flow from the intermediate water tank (27) into the inner member (25)； and a water level in the inner member (25) provided in the side tank (3). A water level detection sensor (29) for detecting that the height exceeds a predetermined height, and a water inlet / drain valve (30) which is an electromagnetic switching valve provided in the lower pipe (21b). When the water level exceeds a predetermined height, the water inlet / drain valve (30) is opened.【課題】少ない設置スペースで運動室ユニットと２つの側タンクとをコンパクトに配置でき、水中歩行、入浴、シャワーが可能である運動機器を提供する。【解決手段】運動室ユニット（２）の両側に接触状態で配置され運動室ユニット（２）に供給したり戻したりする水あるいは湯を貯留可能である側タンク（３），（４）を備える。側タンク（３）は、内側部材（２５）と外側部材（２６）との間に中間貯水槽（２７）を有する二重構造で、外側部材（２６）の上部に接続され中間貯水槽（２７）への給水を行う上側配管（２１ａ）と、内側部材（２５）の底部に接続され内側部材（２５）内への給水あるいは排水を行う下側配管（２１ｂ）と、内側部材（２５）の所定高さに設けられ中間貯水槽（２７）から内側部材（２５）内への流れのみを許容する逆止弁（２８）と、側タンク（３）に設けられ内側部材（２５）内の水位が所定高さを超えたことを検出する水位検出センサ（２９）と、下側配管（２１ｂ）に設けられる電磁切替弁である入水・排水弁（３０）とを備え、内側部材（２５）内の水位が所定高さを超えたときに入水・排水弁（３０）を開く。
