A full body Gait Training Harness for children with disability may be modified for adult use to assist a trainer to teach functions such as walking with a proper gait and crawling. Shoulder straps attached to a torso-encircling belt cross at the trainee's back to eliminate slippage, allowing use on those who have no arms. Leg loops secure the harness to the thighs, rather than through the crotch, for a more secure and comfortable fit.
