For more then 20 years Marion and Alexander Lenz aka "forma fortis" perform and teach acrobatics. Marion began her acrobatic career as a gymnast and Alexander as an olympic weightlifter. In 1992 they started doing acrobatics together in Munich. They founded the acrobatic group “forma fortis” and performed internationally - mostly as duo, but also many times as trio or in collaboration with jugglers, dancers, singers, aerial artists… One of their specialities is adagio acrobatic.
