Abstract: Exercise apparatuses are described. An example exercise apparatus has a lengthwise axis and includes a first shaft, a first frame, a first handle, a second frame, and a second handle. The first shaft has a first shaft first end and a first shaft second end. The first frame is attached to the first shaft first end and defines a first frame passageway. The first handle is disposed within the first frame passageway such that the first handle can translate along the lengthwise axis and rotate within the first frame passageway. The second frame is attached to the first shaft second end and defines a second frame passageway. The second handle is disposed within the second frame passageway such that the second handle can translate along the lengthwise axis and rotate within the second frame passageway.

Abstract: Apparatus and method for the cooling of a rotating cutting blade in a portable circular saw used to cut concrete. A pair of pipes are mounted on opposite sides of the blade extending from a manifold mounted on the base plate. The pipes are provided with spaced openings facing the blade and water under pressure is pumped into the pipes through a hose connection to the manifold so that there is a continuous spray of water against the surfaces of the blade preventing overheating of the blade.
