We developed a device that calculates and displays the center of gravity point and joint moments at the same time with motion. By using this device, stability and physical burdens can be checked with movements. Then dynamic consideration and understanding about the burden outbreaks are obtained. This research paper represents the most suitable method of lift-up motion with a little waist moment. In lifting up a baggage, your waist moment is caused by the gravity and inertia on your body and the baggage. And we offer that you should close in the baggage with your upper body upright before lifting up. This lift-up motion can reduce both of static and dynamic waist moment. In the application of this Real-Time Analyzer to analyze lift-up motion, we examined that closing in the baggage with your upper body upright before lifting up is the knack for reducing both of static and dynamic waist moment in lifting up.
