I've been training with Julien about two years now. It began as an at home training experience, and sometimes we would meet at the gym and do some weight training. Many times we worked out at a local park.
I've enjoyed working out with Julien because of the sometimes unorthodox exercises that he would do. I lost a lot of weight working with him, and increased my 5k race pace. I enjoy that he draws inspiration from many disciplines such as yoga, meditation, martial arts, weight training, parkour, etc.
I think if he had his own gym in a centrally located place it would be awesome. In his gym, he could have jungle-gym inspired equipment in addition to weight training equipment, so we could have a gym (indoors) that would support his style of training. As he grows, perhaps this is what will happen one day :)
