ANSWER: ELEVATOR:
An elevator gets its power from the electric motors that lift it. so you are not physically moving and all you have to do is stand and wait for the elevator to stop at the 10th floor but stairs don't have any power at all. All the energy used to climb them has to come from your muscles.
