Kai is one of the world’s most accomplished fitness experts. His knowledge and experience from training super athletes like Annika Sorenstam, Grant Hill (NBA), Will Asher (Waterski), Eddie Cheever (Indy Racing) and many other pro and amateur athletes is invaluable. Kai has been involved in professional sports since 1985 in his native country of Germany, first as a competitive water skier, then as a performance coach in waterskiing and wake boarding. Kai’s goal is to help pro and amateur athletes of all sports perform at their personal best with longevity and health in mind.

Leveraging his engineering studies, Kai developed his innovative and proprietary workout philosophy of ‘efficiency through perfect movement’ and in 2001 implemented this philosophy to train Annika Sorenstam throughout her playing career (89 professional wins, 10 majors). While training with Kai, Annika gained over 25 yards of driving distance while also improving her accuracy. She went on to be voted Female Athlete of the Year 2 times in a row.

In addition to Annika’s success, Kai’s golfers have won 15 Major Championships and over 150 tournaments on the LPGA, PGA, European Tour and Japanese LPGA. His water skiers and wakeboarders have won over 100 titles including multiple X-Games and Gravity-Games and hold several world records.
