A multifunctional elliptical trainer equipped with steps that have an increased size transverse to the motion trajectory thereof, allowing the foot of the user to be positioned perpendicular to the motion trajectory of said steps, wherein the steps can have an increased length allowing the user to take a wide stance for side-step movement, or normal size steps which can be rotated and repositioned to achieve the same result. In addition to imitating forward walking, the invention allows the user to do the following exercises: Lunges, side steps and crossover side steps, thus training the inner and outer leg muscles.
