As the talented dancer and singer, Shakira sings, "hips don't lie," and if the TRUEFORM RUNNER could sing and dance, it would say the same (it has curves too). There is a noticeable difference in running on the TRUEFORM with the hips in the right position versus the wrong position, which is why the TRUEFORM is a such a powerful tool. Below is a series of pictures and video that compare two different running gaits on the TRUEFORM RUNNER motorless treadmill. One running gait is produced by a "chest-to-bar" position, while the other is produced by a "hips-to-bar" position.

The CHEST TO BAR position is commonly seen in users. If we had to choose one cue to help someone in this position on the TRUEFORM, it would be "drive your hips to the bar." Check out the vertical line on the black wall behind the TRUEFORM. Use that as a frame of reference to help see how these two different gaits are affected by body position.
