Isiah Gray
It amazes him how you can sculpt and define the body with proper food and nutrition! As far as we know, we only have one life. Isiah has found that the best way to live that life to the fullest is doing things that make you uncomfortable, accomplishing things you never thought you could, and always learning. "The mystery of life isn't a problem to solve, but a journey to experience."
