it, you have to schedule it, and, most importantly, you have to do it. no excuses. sitting on the couch, telling yourself you should be doing something will not burn up a lot of calories. if nothing else, get out there and start walking. and while you're out there walking think about a plan of action for a healthier you and get started on it today - not tomorrow!
can you lose weight just by diet alone? sure, you can! but if you want to get fit, you need to exercise those muscles, including your heart. and that heart won't get any exercise if you're sitting on the couch, eating broccoli.
