  1. When did your athletic career begin?
    I began training the Art of Taekwondo back in 1988 at the age of 8 years old.  I started competing in High Performance competition beginning in 1993.
  2. What adversity have you had to overcome as an athlete?
    Taekwondo Kyurugi (Sparring) competitions are divided into weight category. I was often forced to cut my weight throughout my 15 year competitive career. The most weight I cut was about 7kg (15.4lbs) to make weight for 62kg Bantam weight limit.   I had do this in about 4 weeks. Making weight required a very disciplined diet. In 1997 two months after winning a junior National Championship title, I sustained a leg injury while training. I needed two surgeries and was walking on crutches for almost a full year.
  3. How has working out impacted your life?
    As a young athlete and now as a Martial Arts school owner and instructor training and working out has been an essential part of my life.  I am physically stronger, more flexible and energetic. I am confident and mentally strong because I know that if I put my mind to it and work hard enough, nothing is impossible.
  4. How often do you train and for how long?
    When I was competing at a high performance level, I would train four to seven hours  five to six days a week.  I don’t train as often since I retired from competing. However,  I am still running a Taekwondo school full time and teaching five to six classes six days a week. I don’t do the full class with my students but I do try to demonstrate the techniques and do the drills with the class whenever possible.
  5. What is your number #1 fitness tip?
    I believe consistency is the most important aspect in working out.  Set a goal and work out a training plan and stick to it.


Lorne’s take

I had the good fortune of training under David for a 3 years at Jung Ko Taekwondo. He is a stickler for proper form and technique.  David is a very skilled Martial Artist who doesn’t just run through the motions when sharing his expertise.  When you train as long and as hard as David – you’re bound to become a great athlete – which he is.  I also wanted to thank David for sharing a great pic – that’s definitely a unique way to cut an apple :).
