The Helix is a new lateral trainer which means that, unlike other machines, it works the body side to side. This is an exciting advance because instead of just focusing on the muscles of the fronts and backs of the legs, you are also targeting the glutes and the inner and outer thighs—-the total leg 360 degrees.This results in great shaping results for the entire lower body, especially for women who are often looking to tone up exactly the areas that the Helix focuses on. When you are on the Helix, you are working the fronts and backs of the legs, just like when you are walking or running or biking. But the Helix also goes in two different directions. Any machine which helps you use more muscles will translate to burning more calories.
