I agree, exercise is good for you. I never used to do exercise, because i used the excuse that i was too tired after work and never liked waking up early. But now i've got myself into a routine where i exercise everyday after work. I go walking with a friend, at first it was a mission but now i'm in the routine i'm really enjoying it. I def think that it helps to have a friend exercise with you because they motivate you and keep you going, its so easy to make excuses to yourself but when someone else is there is harder.I'm feeling much better in myself since i started exercising and feeling more awake, not as tired! I def think you have to find the exercise that you enjoy doing and stick to it, there are so many diff exercises to do and i think all of them are good, so find the one that you enjoy doing and give it your all.
