usually an hour to an hour and a half however I can speed it up or slow it down depending if I have something to do or just feel like staying more time
To be honest nowadays I work out strictly for fun, you know how when you are young you go play basketball or play soccer for fun? ok thats exactly what I do when I go to the gym, I enjoy the activity of pulling and pushing and feeling the strength in my body, I know enough exercises that I work out intuitively, I dont have goals, I dont care about being bigger or stronger I work out according to how my body feels... I understand not everybody would be able to have this approach but it works for me, Im in great shape, I work out often and I have fun everytime. I work out usually 5 to 6 days a week, if I would feel like not going to the gym then I wouldnt go, but like I said to me is fun to work out.
