No, if you are using ZENO in push-running mode it is not required to always have both hands on the handlebar. In fact, the ZENO handlebar has been specifically designed for one-hand steering to allow a more natural swinging motion while running. During your run, you can try pushing the ZENO with one arm and swinging with the other to adopt a more natural running form. If you keep switching arms you can ensure that both sides of your body are trained equally. Whether you have one or both hands on the handlebar, make sure you always attach the wrist tether strap. When adjusting the handlebar height, the ideal position is level with the height of your navel. If necessary you can always adjust the handlebar height further to find the perfect fit for your running form. Alternatively, you can try hands-free running with the ZENO’s innovative pull-behind feature. This leaves your hands and arms free so you can run naturally, with an ideal posture and no limits to performing your best. Hands-free is safe, comfortable and helps conserve your energy for the best running experience.
