The trainer will offer them to guidance and expertise of physical fitness. So, they can get loss weight and more muscle. It's also offer inbody test and pesonal plan that accordimg to test result of them. And it makes someone encourage and good reinforcement. But to join a gym has some problems. Gym's fees can be costly. It makes waste if someone become busy at some point and unable to make the most out of their gym. And If you exercise at home alone, it's dangers for your body especially posture.
