Avi is designed for runners of all sizes. The adjustable handlebar helps you to find the perfect fit for your running gait. 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. There are some tips you can follow to make your running form more effective, especially when running with a running stroller. Your body should be in an upright position. Avoid looking down at your feet and keep your head up, keeping your gaze focused ahead. Take care that you do not hunch down over the handlebar of the stroller — this is tempting after running for some time, but will have a negative impact on an effective running form. It is not required to always have both hands on the handlebar while using the Avi. In fact, the Avi 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 Avi 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. This allows you to safely stop the stroller when necessary. And keep in mind that it’s not all about pace and performance and enjoy your quality time doing something for you - while keeping your loved one with you.
