I like exercise and meditation. As someone that spent 6 years as a personal trainer and has about 4 years consistent Yoga practice I can say with some degree of authority that there is no 'magic' in yoga it is another form of exercise. Others may disagree but I did enjoy it at the time. I like meditation when I am well or mildly depressed. When it gets worse I find I can't do it. Exercise and meditation have both been studied to some degree in regards to impact on mental health. I remember reading a good study that said that exercise improved symptoms of mild to moderate depression. Anyway, never does any harm to do some reading for yourself on these things. Here is just a little bit.
