My name is Jose Lozada and I was overweight. After college I decided to join the Army but my biggest hurdle was having to lose 3 inches off my waist before I could begin the application process. My goal was to be in the right weight bracket for my age and height (186-196).
Justin Kumai listened to my goals and my story. He didn’t just throw me into an unforgiving workout to show how out of shape I was but instead made my goals clear and provided me a plan to reach those goals.
Justin’s training is tough but rewarding. I really liked how he is very careful about what exercises we do and the intensity.
Because of Justin, I am now at 15% body fat (instead of 28), my weight is 194, I have joined the army, and I have been recognized by the commander of the Lynnwood recruiting center for losing 55lbs. I have more energy, I am in a much happier mood, and I feel absolutely great!
