Subjects will be trained using the sit-to-stand weight-taking machine. Prior to the training, subjects sit in a standard sitting position. Then they will be instructed to take most of their body-weight onto the legs while they standing up where the light bars will be gradually lightened from the red, yellow and green zones according to the level of LLL. Then they stand up, hold a standing position for 3-5 seconds and sit-down with always maximize their body-weight onto their legs during performing the task in which the green zone will always be lightened.

Subjects will be trained using the same instruction and protocol as the experimental group, but without the provision of external feedback.
