Stories about unusual ways to stay in shape always spark interest, and Alexia Craft de la Solx is no exception.
A UK resident has been practicing quad bikes for three years—a special form of exercise in which a person moves on all fours, like an animal. She says it all started by accident. While walking in the park, Alexia saw a man pretending to be a monkey. Curiosity got the better of her, and she approached him. The conversation that followed turned fateful. The man shared his knowledge of nature-inspired movements, and soon Alexia decided to try it herself.
Since then, the unusual hobby has become a lifestyle. Now, she regularly goes outside to "walk on all fours," climb trees, and share her workouts on Instagram, where she has over 100,000 followers.
Despite the criticism, Alexia doesn't mind the ridicule. She says quad biking has changed not only her body but also her perception of the world.
"I love simply exploring the world on all fours. It gives me a sense of freedom and connection with nature that I've never experienced before," she says.
Over three years of training, Alexia has completely rebuilt her body: she's strengthened her shoulders, core, and back muscles, and the soles of her feet have become "almost like those of a primate—strong and stable." Now, the British athlete can easily do pull-ups, climb trees, and feels "in the best shape of her life."
"Before quad bikes, I couldn't do a single pull-up. Now I can lift three times my body weight," she admitted.
Alexia says she's inspired by monkeys and their free movements.
"They show how to use the body to its full potential. We lose this skill when we rely too much on technology and a sedentary lifestyle," she added.
The publication notes that Alexia's videos regularly receive tens of thousands of views, and fitness experts note that quads do develop strength, coordination, and endurance, although they require caution and gradual joint adaptation.
