The present invention is directed to a shovel attachment that is designed to reduce the stress incurred on an operator's muscles, back, joints, spine, and heart during shoveling. The shovel attachment is designed to attach a second handle to a shovel so that an operator may distribute the weight of a shoveled load between both handles and therefore reduce the stress incurred while shoveling. The attachment includes an auxiliary handle having two ends, a first flexible member wherein a portion of the first flexible member extends from both ends of the auxiliary handle, a length adjuster that is attached to the free ends of the first flexible members, and a second flexible member that is attached to each length adjuster and where each end extends to a different coupling member for coupling each end of the second flexible members to either end of the leading edge of a shovel blade.
