Small or very tall people in particular are right to ask this question. Since most fitness equipment is designed for training with an average body height, you should inform yourself as a tall or short person exactly which equipment offers how many cm of stride length. Because of the large pedals, they always offer a certain amount of leeway when it comes to the size of the feet. In addition to the stride length, also consider the individual Q-factor. This is the distance between the outer ends of the treads. The correct Q-factor makes elliptical trainers more biomechanically efficient because hips, knees and feet are optimally aligned and the muscle force exerted on the pedals is increased. When choosing the right model for you, also consider the maximum body weight with which the machine may be used.
