Physical activity is so important! A gym is the perfect place to gain more strengh. You also have a lot of possibilities to choose what you wanna train with. Of course you can also exercise at home but when you pay for a gym, the chance is bigger you REALLY workout then. It’s not about looking perfectly. Perfect is for everyone different anyway. It’s just something you do for yourself only and by the way a good thing to make new friends. Besides, you gain more strenth and more body compfortability. You bring back more O2 into your muscles. Muscle contradiction stimulates the blood circulation. I recommend it for every age. I ve seen old people sometimes more powerful and fit than some younger. Studies showed that people who had a gym membership had a greater health benefit than others. It is not only good for your body, it is also good for your mind and soul. You get very relaxed after a workout. You just feel better, more motivated and more awake in general.
