The aim of this study was to investigate whether bridging exercise with visual feedback effects symmetric weight load and electromyographic (EMG) activity on the trunk and hip muscles between the dominant and non-dominant side. Forty-one healthy subjects volunteered for this study. Tensile force of left and right on the lower extremity and EMG activity of the erector spinae (ES), multifidus (MF), gluteus maximus (GM), and hamstring (H) muscles in the both side was recorded during the bridging exercise under the following 2 experimental conditions: non-visual feedback and with visual feedback. There were significantly decreased difference values of EMG activity on the ES, MF, GM and H muscles and difference tensile force value of between the both sides during bridging exercise with visual feedback than without visual feedback. And the MF/ES activity ratio was significantly increased during bridging exercise with visual feedback than without visual feedback. These findings suggest that the bridging exercise with visual feedback could be effective in facilitation of symmetric weight load and muscle activity on the trunk and hip,
