Good exercises include walking, running, swimming, biking, or a gym workout. A nice mile-long walk at a decent pace can work wonders. For those who are bored easily, you might want to mix your routines…bike one day, walk the next, go to the gym the next day. In addition, instead of hiring someone to do your gardening, do it yourself. Do the same with home maintenance. You can burn off a lot of calories climbing a ladder, digging, raking etc.
