Looking for a Bauchtrainer I finally found this Power Roller. Because of my stature is tall and strong. It was difficult to find a device that can deal well with the large and strong people. The plan was to complete daily yes a few workouts. So finally the abdominal muscles are taut and especially the fat is broken down, I needed such a device.It weighs only 998 g yes and the structure is simple. This is important because otherwise you might suffer the motivation.The frame is stable and confidence inspiring. The headrest is surely the most important part of an abdominal trainer. Here, the headrest is perfect. It is flexible and the head lies comfortably on. Thus, the spine and the back are not overloaded. During training I realize that my hip is supported when rolled up in attitude. It is as inexperienced beginners not so easy for me to learn liquid motion sequences during muscle training. This muscle trainer gives me the feeling that I can do it. Ab Workout asks of something. Simply sit ups without aids are heavier. The unit I have learned it. At first, I pulled more with his hands, instead of working with the torso and hips. My favorite exercise is: bend your legs and put your feet on the cross. Then lift the upper body and head so far that one is just above the bottom. So you and wonder where all are muscles that respond to this exercise. This applies first of all workouts with this device. Just Untrained have since completely new experience. advantages - The padding of the frame is very pleasant - the headrest is large - the support for the elbow is very convenient - solid frame - the attitude during abdominal workout is comfortable and effective - a wrong posture is prevented The design of the power scooter is interesting. Not only a frame with headrest, but a semi-circular shaped rolling surface makes the device compact. Clever is the idea of the profile on the rolling surface. This provides security and maintenance. The color scheme of black and aluminum is solid and looks classy.
