Actually the engineer behind the suit developed it exactly for people like us:

"The development of a truly wearable anthropomorphic exoskeleton was the goal of Yoshiyuki Sankai when 10 years ago he started working on HAL, the Japanese system that will be available in November 2005. Sankai, a professor at the University of Tsukuba, 60 km northeast of Tokyo, says HAL (short for Hybrid Assistive Limb) is a full-body suit designed to aid people who have degenerated muscles or those paralyzed by brain or spinal injuries. HAL-5, the system's fifth generation, made its debut this past June at the 2005 World Expo, held in Aichi, in western Japan."
