The invention provides a health management system and a method, wherein the system and the method relate to the technical field of life health. The system comprises a health management platform, a user terminal and a movement management terminal. The health management platform comprises a movement plan generating module and a movement plan improving module. The user terminal transmits a body improvement expectation to the movement plan generating module. The movement plan generating module acquires body condition information of a user, and generates a movement plan in a preset time period forthe user according to the body improvement expectation and the body condition information. The movement management terminal adjusts the movement plan and transmits the adjusted movement plan to the user terminal, and acquires movement data of the user in a sub time period in the preset time period. The movement plan improving module acquires the body condition improvement information of the user after movement, and generates a movement improvement plan in a residual time period according to the movement data in the sub time period and the body condition improvement information. Therefore the user acquires the effective movement plan which is suitable for the user, thereby realizing a high-efficiency health management purpose.
