It’s a good idea to book in with a PT or book a tour of the gym before you start to get a feel for the space and gain a basic understanding of how everything works. That way, you won’t be starting from scratch, and it’ll help you to feel less like a newbie when you start using the gym.
Buddy up! If you're nervous about working out alone, bring a friend or family member who also wants to get fit with you so you can encourage each other and hold yourselves accountable. Plus, it’s fun! The gym shouldn’t be a place you dread entering, so make it enjoyable by doing it together.
Everyone has to start somewhere, so take it slow! Even a couple of half hour sessions a week is a great place to start. As you progress, you’ll find you can do more for longer periods of time, but work your way up gently. The last thing you want to do is injure yourself!
