At first it's going to feel like a job, but once you get into a routine and begin to get used to it ,you will feel the effects. The hardest part is sticking with it at the start. Exercise doesn't have to just be about hitting a crowded gym (which can cause many peoples insecurities to rise), but it can be much more appealing. You need to find an activity that you are somewhat interested in: biking around town, jogging (or maybe start with walking), swimming, or joining a team sport. The effort you put in will pay off, and eventually it won't feel like as much of an effort but rather a relief and break from the stresses and challenges of day to day life.
