I am new to this and I don't understand what do
Most fitness facilities train their staff to help new members on becoming acclimated with their facility. A few provide personal trainers (sometimes at a fee) to assist you in obtaining your goals. You should not feel awkward seeking out assistance from a “coach”. Especially if you are new to fitness training. Unfortunately, there are some clubs that do not provide this as a new member orientation. If your club does not, I recommend you seek out someone to assist you in using the equipment. If, for nothing else, the assistance you receive can help you avoid injuries from improper use of the equipment. It's important for someone new to learn proper technique. And, learning how to use new equipment will provide more opportunities for you to reach your goals. After some a period of orientation, you should feel comfortable enough to train on your own. That does not mean that you can't ask for assistance in the future. If you're unsure about anything in the gym, you should seek out someone for assistance. If no one is willing to help, it may be time to seek a new gym.
