Lifting Things. Ergonomics is not just for computers. Anything we are working on should be working within easy reach, preferably in the same area as a strike zone while playing baseball (knees to chest and close in front of the body). If it’s not, consider moving it permanently or temporarily while it’s being used. Work stands lift an object to a specified height. Lift tables move the working height from high to low on a single item. Step stools bring a person up to a higher working height.
