I have a gym crush and he seems really unapproachable

I started going to this gym 3 days ago and this guy caught my eye the second I walked in. He looks really good and I’m sorta attracted to him. He’s always with his 2 guy friends and doesn’t really look elsewhere or in my direction. He seems very unapproachable but I really wanna get to know him but I’m worried he’s super cold or he’ll just shut me off saying he has a girlfriend and be super mean. I really wanna get to know him. What do I do? I can’t walk upto him because he’s always w his 2 friends!!!
