you will still have to move it in the direction you need it to go though.  in hip, or in body, the z (for exapmle) is set in that it will return to that point.  i would delete the z frames from one section, then the other to find out which one is holding that motion (not saving this)  then reload the animation, figure out the difference in the distance covered in the z from the first step to the last.  then reload the animation again for the second cycle, add the difference to the z values in the second cycle.  z or x, whichever way, possibly at an angle will make you use both z and x, but just use the calculator and add those values.
