What is your goal (aim, purpose)?
It could be to lose weight or run faster. Maybe you want to build lean muscle and get stronger. Or simply walk more to stay healthy.
Whatever it is, it's important to have a goal to move towards.
Goals help keep you motivated and accountable. It doesn't have to be specific, it could be general, as simple as showing up for a workout a few times a week.
Short term goals are very attainable. Think of something you'd like to be better at in three to six months and set your sites on it! Write it down, keep a training log and before you know it you'll be there!
