A physical therapist in his non-Ninja time, Greg has been adapting Ninja training techniques to help his patients, including Garrett Rogers.

10 year old Garrett was hit by a drunk driver while at baseball practice, leaving him with a fractured skull and a brain injury, to name just a few of his injuries. Working together with Fleming, Garrett has been working hard on an incredible recovery.

You have to watch their story above.

Amazing job by both these true Ninja Warriors!
