An information processing apparatus includes: a preparation device preparing information on a body posture; an acting force meter measuring a first acting force the body applies on a first object; a myoelectric potential meter; and a processor acquiring the information on the posture, acquiring information on the first acting force measured by the acting force meter, acquiring information on the myoelectric potential, setting an initial value for a second acting force the body applies to a second object other than the first object, estimating a muscle activity state corresponding to the posture, the first acting force, and the second acting force, repeating updating the second acting force such that a difference between (i) a muscle activity state determined based on the myoelectric potential and (ii) the estimated activity state decreases, and presenting the second acting force when the difference is less than a predetermined threshold value.
