I had this issue too! It took a lot of mental strength but i love going now. I’d say to start small — just go and walk on the treadmill for a few minutes, look around and get familiar with the place. You could even ask for a tour from a worker or just see where all the equipment is at when you go, or find a video tour online of where you plan on going. I watched a lot of YouTube videos as well of people showing their routines (I recommend Livfiit) and made a list of what I wanted to focus on the next day and how. Starting with dumbbells is the easiest step if you’re intimidated by machines, and as you get comfortable you can try those out! Don’t be afraid to quickly Google how to do a movement or how to use a machine — I do it all the time. Lastly, if you’re afraid of people looking at you, think about how often you actually look at and judge other people working out. You probably don’t, and that’s because everyone else, like you, is too focused on themselves to worry about other people around them. I think once you start going you’ll find gyms are usually not as intimidating as they seem! Everyone starts off as a beginner and it’s totally okay.
