Walden is best known in the UK and US for his role as the expert fitness instructor on
VH1's and
ITV's primetime shows
Fat Club and
Celebrity Fit Club. In the 2007 season of
Fit Club, during a heated exchange, contestant
Dustin Diamond (the actor commonly known as
Screech from
Saved by the Bell) challenged Walden to "physical combat". Walden responded to the challenge after Dustin refused to follow their diet and exercise plans. He is a father of two children; one boy, Harvey V, and one girl, Tiyauna Denise. ==References==
