I think that having a goal is a very good thing to have when you are exercising. It gives you something to aim for and a reason to stay consistent. If you don’t have a goal, then you are just kind of showing up and not really pushing yourself to go to the next level. It is possible for some people to stay consistent and push themselves without having any goal in mind, but I have found that most people including myself need something to work towards.
I have had many goals in the past; coming back from injuries, finishing a triathlon, running a half marathon, running an obstacle course run, lifting a certain amount of weight, putting on certain amount of muscle, etc etc. I trained differently for each of these goals, and they all kept me exercising on a consistent basis. I don’t like to fail and having a goal keeps me competitive with myself. I want to prove to myself that I can do anything that I set my mind to.
If you don’t have a goal and you find yourself being inconsistent with exercise, then I would set a goal. The goal can be anything you want it to be, it’s your goal and it should be important to you. It should also be something that is not easily achieved. It should be a little challenging but not impossible to complete. The purpose of a goal is to push yourself a little outside of your comfort zone. If you easily achieve your goal without putting in a lot of effort, then you need to make your next goal a little harder.
