Compared with traditional crosstrainers which have only one type of movement, the biomechanics of Crossover simultaneously involve the legs in extending, abducting, flexing, and rotating actions. Compared with Vario, where your own movement changes the length of the stride, the direction is lateral and the maximum extension of each step is fixed. Different from a treadmill or running on the road Compared with treadmills or running outdoors, Crossover does not require a high degree of coordination, because the movement is guided. In addition, because there's no contact with the ground, there is less impact on the knees and the joints in the foot. Safe for knees and ankles When you begin to exercise, the inside edge of the platforms is higher than the outer edge, which prevents you from assuming an incorrect posture that could cause improper rotations, ankle sprains, or problems like valgus knee. The motion of the equipment itself helps you keep your lower limbs in a proper line. Suitable for rehabilitation The 700 MD and 500 MD versions of Crossover are certified by European Community law 93/42 addressing medical devices, and are suitable for use in hospitals, sports centers and rehabilitation facilities as support for treatment and muscle rehabilitation. Safe and suitable for everyone According to a study by the Technogym Scientific and Medical Department, men and women older than 60 who have used Crossover have demonstrated lower levels of cardiac fatigue and improved balance. With UNITY training becomes as engaging as ever Thanks to the UNITY digital platform, you can turn the machine you use into your personal device for the entire duration of your workout.

It is now possible to access social networks and preferred Web contents, participate in your gym's challenges, manage your workouts and monitor your indoor and outdoor activities. With UNITY, this and much more is possible. What is the movement of Crossover like? The platforms and levers move together with a motion that is: Alternating The directions alternate: if you're pushing the platform with your right leg, you have to pull the lever with your left arm and vice versa. Convergent for the arms The levers follow a guided, converging and diverging motion (they don't move in a straight line): the proper motion is to pull one toward you while pressing the other outward. Lateral and three-dimensional for the legs The platforms involve the legs in a lateral motion that moves in three directions. During exercise they move backward, outward and rotate so that your legs extend to the rear, shift toward the outside and rotate. Intuitive and flexible The biomechanics of Crossover make the movement intuitive. When you reach the "dead spot" of your motion and need to start moving in the other direction, you can do so easily and without struggle because the platforms are designed to make your movements easier.
