Low back pain (LBP) is a common cause of job-related disability, usually related to idiopathic spine injury such as muscle sprain or so called 'slipped disc' due to lifting heavy object, which has around 80 % occurrence among injuries at the low back. That represents dual economical effect to society in form of reduced working force, and simultaneously the higher cost of the health care. In some cases the person face the risk to lose its job due to inability to carry heavy objects. Research already done doesn't suggest any solution how to prevent LBP and injuries. Ability to lift a heavy object has almost every healthy person but not all have the right physical condition to lift heavy objects. The presented work briefly shows the difference between two subjects with different physical background. Subject A represents the ordinary young lad visiting a gym while subject B represents young athlete with regular trainings for competition. Both subject had an experience with deadlifting, and were knowledgeable of the correct posture. Their lifting trials were recorded and processed to obtain forces, moments, angles, velocities, and acceleration of each segment of lower limb. An observation and some results are presented in this paper.
