Reiner Grootenhuis

As a teenager Reiner started learning the Chinese martial art Tai Chi from one of his school teachers. Later, during his psychology studies he learnt the Chinese martial arts Weng Chun developed by the martial monks of the Southern Shaolin Temple, to protect themselves from attacks by pirates and robber. After he finished his master's degree in psychology he founded a martial arts school in his hometown in Germany, which still exists today, run by its second owner now.

Due to his workload as a top executive at one of Germany's largest utilities, his activities as a university lecturer for Marketing as well as his MBA part-time executive studies, Kung Fu and other sports were taking a back seat.

To bring his body back to life, he started doing Pilates. In parallel to his day job he did the BASI Comprehensive Teacher Training with Miriam Friedrich Honório. During his Pilates education 2010 - 2011, he founded the internet forum and some months later, following a wish of Lolita San Miguel, the pilates-contrology-forum group on Facebook, which today counts over 5000 Pilates teachers. Today the forum has additional groups like an events group (4500 members), a research group (300 members) and a marketplace to sell Pilates equipment (3300 members). In March 2012 Reiner quit his former job and opened his own Pilates studio in Toenisvorst, only 25 km away from Joseph Pilates birthplace Moenchengladbach. June 2014 Reiner started his mentor program with Rael Isacowitz.
