If you are going to the gym for the first time, of course, you can ask the coach to teach you, and then he will sell you lessons. Generally, no coach will teach you how to train for nothing, but there are still some tips. Generally, there will be two courses in the gym, and the touring coach will take you, mainly to teach you the use of equipment and the training of your muscle groups. When you go, you can run on the treadmill first, and then do strength exercises.
