Gabriel was born on 1976 in Houilles, France. Later on, the whole family moved to Jaca, a village in northern Spain where he started practicing figure skating. At the age of 14, he decided to try free climbing inspired by the surrounding mountains. He dedicated his life to this sport for more than 15 years, setting routes of 8B+/C (5.13D/5.14A) and competing at regional, national, and international level, winning several prizes along the way. In 2005, he became a Professional Firefighter. Later on, he also became a Certified Street Workout and Calisthenics Trainer.
After watching a contemporary circus show in 2006, Gabriel felt compelled to explore his artistic and creative side within the world of aerial acrobatics. He started practicing aerial silks but quickly moved on to rope and straps.
