If you want to get the most out of your gym sessions, you need to set an achievable goal for yourself. Knowing what your target is will encourage you to keep going to the gym, to achieve the goal that you have set for yourself. Once that goal has been realized, set yourself another one, which is a little harder, but still within the realms of possibility. It is essential that your goals are achievable, or you will be more likely to turn away from them. Goals can involve losing a set amount of body fat weight, managing to run for a certain distance on the treadmill, or whatever other goals you think will keep you going back to the gym.
