Electronic device and wearable device for providing exercise program, and control method of the same

A control method, comprising:

• providing a first exercise program of a first exercise period by changing an exercise intensity within an initial exercise intensity range to a user wearing a wearable device comprising a frame configured to be worn on a body of a user and a driving module configured to generate an exercise load applied to said frame for a motion of the user for exercise based on controlling the exercise load of the user through the wearable device, the first exercise period corresponding to a warm-up exercise period;
• measuring a first posture score of the user while the user is performing the first exercise program using the wearable device, the posture score being determined based on one or more posture factors specific to a posture required by the first exercise program;
• determining an exercise ability of the user for the first exercise program by comparing the first posture score to a posture boundary value set for the first exercise program;
• setting a personal exercise intensity range of the user based on a result of the comparing;
• and
• providing a second exercise program of a second exercise period based on the personal exercise intensity range, the second exercise period corresponding to a personalized exercise program period different from the warm-up exercise period of the first exercise period,
• wherein the operation of providing the second exercise program comprises:
• measuring a second posture score of the user while the user is performing the second exercise program using the wearable device;
• and
• in response to the second posture score being out of a control margin of the posture boundary value, adjusting a current exercise intensity of the second exercise program.

A wearable device to be worn by a user, the wearable device comprising:

• a leg support frame configured to support a leg of the user;
• a driving module, comprising at least one of a motor and circuitry, configured to generate an exercise load applied to said leg support frame for a motion of the user;
• and
• at least one processor configured to:
• provide a first exercise program of a first exercise period by changing an exercise intensity within an initial exercise intensity range based on controlling the exercise load of the user through the driving module and leg support frame, the first exercise period corresponding to a warm-up exercise period;
• measure a first posture score of the user while the user is performing the first exercise program via the wearable device, the first posture score being determined based on one or more posture factors including at least one of a pitch-related posture factor indicating forward/backward tilt of the user's pelvis, a roll-related posture factor indicating whether the pelvis is parallel to the ground, a yaw-related posture factor indicating pelvic rotation during motion, a posture factor based on a distance between the user and virtual content, and a posture factor based on angular velocity;
• compare the first posture score to a posture boundary value;
• set a personal exercise intensity range of the user based on a result of the comparing;
• and
• provide a second exercise program of a second exercise period based on the personal exercise intensity range, the second exercise period corresponding to a personalized exercise program period different from the warm-up exercise period of the first exercise period.
