A measuring kit for determining parameters indicative of a DR (diastasis recti) condition of a patient includes two components: a distance measuring component adapted to measure a distance DR parameter and a depth measuring component adapted to measure a depth DR parameter of a user. The measurements obtained with these components are compared with standard measurements obtained from other users and used to indicate or determine the condition of the user. The kit is particularly helpful in monitoring the progress (or lack of progress) of a person performing certain exercises designed to alleviate DR conditions.
