Benefits of Fitkit Double Exercise Wheel Your spine maintains its perfect position when your core muscles are well-balanced. This gives you good posture and provides a solid basis for the rest of your muscles and body movements. It helps to prevent lower back pain as well as improves sports performance and every day movements such as standing on one foot, reaching over your head etc. When you exercise with an exercise wheel you have to support your whole body weight while you roll, this forces your core muscles to work together and contract as a group, whereas exercises that target only your abs or your back may result in a core muscular imbalance. How to Use: Hold the Double Exercise Wheel with both hands and kneel on the floor. Now place it on the floor in front of you so that you are on all your hands and knees (as in a kneeling push up position). This will be your starting position. Slowly roll the wheel straight forward, stretching your body into a straight position. Tip: Go down as far as you can without touching the floor with your body. Breathe in during this portion of the movement. After a pause at the stretched position, start pulling yourself back to the starting position as you breathe out. Tip: Go slowly and keep your abs tight at all times. Caution: When using the Fitkit Double Exercise Wheel for the first time start slowly and gradually progress as your core strength increases. Because it works your core hard, you do not have to spend a lot of time using the roller, a few minutes a day will strengthen your core. This exercise is not advised for people with lower back problems or hernias. Variations: If you are advanced you can perform the exercise moving the ab roller to the sides in a diagonal fashion as opposed to straight forward. This version places more emphasis on the obliques.
