  • Patent number: 10363448
    Abstract: A liquid buoyancy muscle training device includes a liquid receiving tank receiving and holding liquid therein. A buoyantly submergible member is buoyantly submergible in the liquid contained in the liquid receiving tank and includes a regulation chamber formed therein. A bottom pulley is mounted inside the liquid receiving tank. A rope is connected to the buoyantly submergible member and wrapped around the bottom pulley and extends upward to project outside the liquid receiving tank. A liquid regulation tank is connected through a liquid supply tube to the regulation chamber to allow liquid to flow therebetween. A gas supplier is connected through a gas supply tube to the regulation chamber to selectively supply gas into the regulation chamber to change a ratio between liquid and gas inside the regulation chamber so as to change buoyance applied to the buoyantly submergible member by the liquid contained in the liquid receiving tank.
