Hennie Terreblanche

Co-Founder & Head Coach

  • CrossFit Level 2 Coach
  • CrossFit Semifinal Athlete
  • 11th Fittest in Africa

Hennie started training in a two-car garage in 2022 and, alongside Kalinka, went from unknown to the CrossFit Semifinals stage — twice — earning a place as the 11th fittest in Africa. He cares more about the member who leaves able to hike with their kids than about any leaderboard, and coaches accordingly.
