Post exercise

The feeling you get when you finished exercising,like you feel with a lot of energy,and can do anythings.Like for example when you have been eating a lot of junk and not been exercising in a long time.But when you start to exercise,the feeing you get after,its like if you have loosen weight and look great.You feel healthy and amazing.Somehow our bodies just feel different after you exercise.Some of us think we gain muscles,when we lift weights or that our legs look great after you run in a treadmill.Even thought it's not really like that or like when you do crunches and after you check your self in the mirror you think your stomach is flat.Our minds trick us in believing that we look different,while other people see us the same.I don't know if our mind just does it,to make us feel better or our body did actually feel different.I don't know if it the same for everyone but that the feeling I get after I exercise.
