No movement, no work, no energy spent.  If you didn't move it, you
didn't use energy (sure felt like it though??  :o)   ) so no work was
done, no heat generated.  If you stand still, gravity is acting on you,
your feet don't burn up from holding you up (providing the normal force)
or if you sit on an inclined surface, your butt doesn't heat up either. 
The gravity is still pulling, there is still a force acting on you, but
as long as no work is done, no lost energy, no heat.
