I walk about 20 km a day, preferably five times a week + what I walk to and from school and when I'm shopping for groceries.
When I'm at my parents' I go to the gym three times a week plus swimming two-three times a week as well + some walking while delivering newspapers.
Then I take sit-ups, push-ups plus minor sets with weights as well as minor Pilates routines daily.
I make a habit of walking to wherever instead of taking the bike or the bus in general.
I'm at the point where I become restless if I don't exercise at least a couple of hours a day, which at times can be quite bothersome.
