In terms of spinless fermions via the Jordan-Wigner transformation along a snakelike path and spin waves modified so as to restore the sublattice symmetry, we investigate the static and dynamic properties of two-leg antiferromagnetic Heisenberg ladders. The specific heat is finely reproduced by the spinless fermions, whereas the magnetic susceptibility is well described by the modified spin waves. The nuclear spin-lattice relaxation rate is discussed in detail with particular emphasis on its novel field dependence.
