An exercise equipment handle permits a user to perform inverted rows with a vertical bar positioned above the user, such as on the barbell part of a Smith machine. The handle can be hung from the barbell part and the user can be positioned underneath. The user can grip the handles and do inverted rows with a neutral (palms facing) grip. In some embodiments, the handles are close to provide a narrow grip. The handles are typically turned out at an angle and are suspended on a cross-piece. The user is able to do inverted row exercises safely, without the lower back strain usually associated with rowing-type exercise.

The invention relates to an aquaculture feed-scattering fishing boat capable of salvaging dead fish rubbish and achieving uniform oxygen and deodorization. The aquaculture feed-scattering fishing boatcomprises a boat body device, a salvaging device and a feed-scattering device, wherein the salvaging device is installed on the front side of the upper end of the board body device, and the feed-scattering device is installed on the rear side of the upper end of the boat body device.

A manually powered rowing vehicle is provided. A chain is wrapped around a portion of first and second free-wheel wheel sprockets, which can spin freely in one direction but not the other. The first free-wheel drive sprocket drives a rear wheel. The second free-wheel drive sprocket connects to one end of a lever arm, which pivotally connects to a frame. When the rider pulls the other end of the lever arm towards their body, the first free-wheel drive sprocket grabs the chain and pulls the chain forward. The chain in turn pulls the second free-wheel drive sprocket, which rotates the rear wheel forward. When the rider pushes the lever arm away from their body, the first free-wheel drive sprocket spins freely to allow the lever arm to return to the pull position without moving the linked chain or the vehicle. Various embodiments for steering the vehicle are also described.
