Elastic load suspension systems and methods are disclosed. Embodiments include handles with springs to reduce peak forces and reduce the overall energy required to carry a load. Some embodiments include handles that connect to loads, where the effective spring length statically deflects at least 2.5 and at most 18 inches, and in some embodiments approximately 5 inches, when carrying the load. Alternate embodiments include elastic suspension handles that are lightly damped, such as those with a damping ratio of at most 0.5. Still further embodiments include elastic suspension handles that elastically suspend loads and have a natural frequency that is less than the locomotive frequency of the object carrying the handle, such a less than the typical human walking frequency of 2 Hertz.
