I am very surprised at what a difference it makes to increase my weight ratio from 50% to 55% on the AlterG. No surprise that once again it was a real struggle to maintain a solid running pace at 55% body weight.
The first mile on day one was tough. I had some regression in the feeling n function in my left leg and could barely feel my heel strike. It was a struggle to keep up any type of speed and I spent a lot of time just focusing on getting mentally past the discomfort. This seemed to do the trick and the second and third mile proved much less difficult. I questioned my decision to move to the higher weight and considered going back to 50%, but I just couldn’t fathom the thought of going backwards so I committed to the discomfort and decided to stay the course.
By mile four on the third day, I was still feeling heavier and unsure of my decision to go to a higher weight. I was still struggling and my left foot was really hurting under the impact of the extra weight. Instead of stopping, I briefly shifted back to 40% weight, which is so easy to do on the machine. I only needed a few minutes at a lower weight and my foot recovered enough to finish out the week at 55%. I may not ready, but next week’s goal will be to try for 60% weight.

Next week’s goal: Move to 60% body weight varying speeds.


















The AlterG Blog
Welcome to the AlterG Blog! This Blog is part of our effort to create a community for AlterG customers, patients, clinicians, researchers and fans to talk about rehabilitation, training and helping people achieve their personal health goals. We have been working on the launch of the Blog for some time now because there are so many great stories and insights that we can all share with each other. Thus the creation of ‘Elevated Thoughts’.
Through the blog posts we hope to provide a myriad of patient and athlete experiences, rehab and training protocols and success stories from Anti-Gravity Treadmill users, that can be shared across the world.
