"Charles offers personal fitness classes for fitboxing, self-defense, boxing, and Yi Qui Tao. His rate of 50 CHF is quite reasonable, much cheaper than other private lessons or personal training. He discounts for larger groups as well, but no more than 3-4 people in class size, I think. I attend his Yi Qui Tao classes regularly and it's great. He can do private lessons with you at his gym in Eaux-Vives, even if you are not a member there."
