for those who dunno, i normally go for my physical exercises i.e. morning walk and line dance, after i send the kids to school. i believe that we don't have to come up with a big sum to exercise at the gym or something. sometimes their fees are too much! do correct me if i am wrong.
you people can just go for walking/strolling will do. for the timing, it depends on the individual. for me, i prefer to go in the morning for the cool fresh air. read on about the benefits of walking here.
