Before gymnastic class I just found Nanako Tachibana warming up that is the right thing to do before excercise.Indeed you should exercise everyday for your healthy.Because Exercise has a cumulative effect. You can get the same benefits from working out in three, 20-minute intervals a day or building up your hour in five-minute chunks. That's is very rarely informative words from me LOL. Lets see the example from Nanako Tachibana pics below. :)
