Running Hills with Wu made me a much faster person, he pushed me to my limits and it made me a faster defensive player. Wu put me through hard workouts and it made me much stronger, it helped me to stand my own in basketball games and be physical. Training with Wu doesn’t just make you stronger it makes you a better person wanting to work harder, pushing you to your limits. Wu’s training benefited me a lot in my sports career.

Wu is a great person with so much knowledge. He has made me become better mentally and physically and helped me reach my goals. A great example of this is when I first started working out with Wu I could barely squat the bar with a 10-pound plate on each side and barley bench the bar. But now with Wu's help and constant grinding I can now bench over 130 lbs. and over 250 lbs. Wu drives me to be great every day and I could ask for a better mentor and friend.
