Doing core exercises has always been the toughest workouts for me due to having acute lower back issues. Ironically, I learned having a weak core is the main contributor to lower back pain. I'm embrassed to say but I was unable to carry my children in my arms for extended periods of time without suffering from excuciating pain in my lower back. As a father not being able to pick up and carry my children in a life or death situation is my greatest fear. I became obessed with strengthening my core but all the exercise movements and typical equipment did not make my efforts easy. The problem was most equipment or exercises recommended for core strengthening requires the use of the lower back throughout the exercise movement. With a background in mechanical and industrial engineering, I decided to pursue a practical solution, put the body in the most optimal starting position for engaging the abdominal core muscles while continously supporting the lower back throughout the exercises along with shifting the center of gravity away from the lower back and lumbar area. In pursuing to create an aide to put users in this low stress bearing position the Gravity Mat was born! It has truly been a heaven sent for my lower back and core. Now, I'm sharing this aide that helps me with the world.
