The sliders allow for smooth movement of the joints and muscles, and because you remain in contact with the ground throughout the exercises, there are no impact forces acting upon the body. The gliding motion helps you easily achieve your optimal range of movement and works multiple muscles whilst engaging the postural stabilisers. Reducing stability during traditionally static exercise such as lunges, squats, push ups and bridges increases their effectiveness and can also be a good work out – elevating the heart rate allowing two types of training in the one exercise.
