Is Aikido a good workout physically and mentally?

I hear different answers on this one. Some say you can get a good workout while others say you won%26#039;t break a sweat. And how is it emotionally benefical?|||It depends on the school. Some do and some don%26#039;t. I would go and watch a class and even participate in a trial lesson to see what%26#039;s right for you. I take Shotokan karate and its an excellent workout.
