Arranging the equipment in a circuit and using a set alternation of intensive training phases with short recovery phases facilitates effective and time-saving training. Using a circuit, a wide range of training objectives can be achieved quickly and lastingly. And incidentally, circuit training is fun and creates more variety than traditional strength or endurance Training. The circuit promotes social contact and those doing training motivate each other. The milon circuit is also a great concept for studio operators with strong commercial impact. A maximum of through-put is possible at a minimal space requirement. A higher support and service level can be achieved with even less staff. This in turn increases customer satisfaction, and fluctuation decreases. The milon circuit thus combines two essential factors for happiness: optimal training and optimal utilization.
