Elet1Growing up nearby, outside of Hagerstown, Md,  Elet Hall spent his time running, climbing, and jumping through the woods.  As a teenager he began practicing and later coaching  Parkour. Originating in France, Parkour (French for ‘obstacle course’) is called the art of movement, and is known for its practioner’s abilities to climb, jump, and flip over everything in sight. However, not just extreme or cinematic, parkour is a  personal discipline of physical self challenge that strengthens the relationship between mind, body, and spirit.

Elet credits this style of training, specifically in natural settings, for his success on the American Ninja Warrior course. Participating in 4 seasons of the obstacle course challenge he qualified for the National Finals every year, often with the fastest completion times, and also represented Team USA on the international Ninja Warrior Challenge.

Elet has coached parkour around the nation to adults and children alike and is also an Ambassador for the Bay Area Lyme Foundation, a research foundation striving to make Lyme disease easy to diagnose and simple to cure.

Drawing from a background of climbing, backcountry snowboarding, martial arts, fitness, and parkour Elets believes that outdoor exercise is essential for human health no matter your age or previous experience. He hopes to help students increase vitality, strength, and agility, reduce pain, and gain personal insight through individual challenge and experience.
