The Saddle Encourages Proper Running Form
The Saddle is not only a revolutionary way to mount your iPhone on your wrist so you can view your workout stats with ease, but the position of the mount also encourages proper form.
If The Saddle is properly mounted, then it should be on a plane with your thumb. That way, if you keep The Saddle facing the sky, you will be keeping your arms on a plane and not swinging side to side. Also, with the way the Saddle is positioned the easiest way to see it while running is by keeping your arms at a 90 degree angle.
