This aims to provide passive exercise equipment capable of securing constant sense of use so as to avoid variation in depressing feel against sole-surmounted parts irrespective of body type difference among users. The equipment has a seat 2 for resting a user M on the buttocks, right and left footstools 3 for resting the right and left soles of user M sitting on seat 2 on, and a seat driver 5 for changing the position of seat 2 position to change load balance added to seat 2 and footstools 3 by user M, thereby changing the users own weight acting on the legs. Each footstool 3 includes a sole-surmounted part 4 which a sole is placed on and meanwhile can be moved up and down, an elastic device 6 for biasing sole-surmounted part 4 upward and a bias adjuster 7 for adjusting an elastic coefficient of elastic device 6.
