From a young age, Forian Zitzelsberger was fascinated by movement.

“My father was a big influence,” he told me over the phone last Friday. “He was a sports teacher, and he started very early to help me understand biomechanics. My father also played a lot of tennis, a lot of racquet sports, and imparted on me the importance and meaning of athletic movement.”

Growing up in a sports-mad family, Zitzelsberger turned that fascination into his life’s work, becoming one of the most sought-after performance coaches in tennis and co-founder of Integralis Physiotherapie, which he co-founded with fellow trainer Daniel Pohl.

“We called our company Integralis because we integrate everything into achieving maximum performance: strength and conditioning, physiotherapy and osteopathy, sports mental training.”

Having worked with Top 10 stalwarts Kevin Anderson and Petra Kvitova, his latest project will be to bring Naomi Osaka from maternity leave and back onto the Grand Slam stage.
