I used to not like to exercise. So many reasons have been tapped here. don't want to change my clothes, takes to much time and effort. Don't want to get all sweaty, and go the rest of my day with bad hair. Way to tired to do it in the evening when I don't care how I look.
So the most I would do is walk. I would go for walks in the evening.
Used to love going to the gym. havn't been in years. What I really wanted to be able to do is run! I love that feeling when your pushing yourself, that burn in the chest that says your working. Love the feeling of my muscles working! I jog, have a treadmill and will just go till I drop. usually about 2.5 miles.
I don't care if I get sweaty anymore. don't care if someone sees me in my spandex. Don't mind changing into comfortable clothes.
I just really makes me feel alive to be able to just GO! with the kids all back in school. including my youngest. I am going to try the gym again.
