First interview in a gym, any suggestions? What do I have to bring?
Unless they offering you a salaried position I wouldn’t quit the other job just yet. But at the same time it will be difficult for you to build a business in this industry if you don’t have the flexibility required to train enough clients to make a living. You might want to look for gyms that are looking for part-timers. If you have a full time job already, training a few extra hours a week would be a good supplemental income for you.
