The gym associated effort and constancy, certainly to notice the results will require a previous work, which in principle can be hard and thankless, since the results are not seen immediately, rather the opposite. Sport is always healthy in all its forms, with restraint, knowing our limits, and not to exceed them, the gym is a good option, even at holiday time, always directed by the instructor, which we can advise on the mode and way of doing different exercises, using different instruments. It can be a way of forcing ourselves to exercise, because you will have a certain obligation to support, anyway, each person has to evaluate the time available and if you may be interested in this form of exercise and not choose some other model.
