Willie Engelbrecht, professional cyclist and four time winner of the Argus cycle tour in 1988,1989,1990 & 1994: "After a cycling accident in March 2005, I used the Chasek DVD's as part of my recovery program.  After just three months, I had recovered fully and was also able to rebuild my fitness level. After a couple road rides I was able to compete in a competitive 250km MTB race. I can certainly recommend the Chasek DVD's, they are an invaluable training aid." Willie is arguably one of the greatest professional cyclists that South Africa has ever produced.
