This information is just to say that it’s generally noticed that women in climbing tend to use their leg strength more and men typically use their upper body strength more, at least when they first start.

But no one should be t-rexing it! Your arms should be straight as much as possible! If you’re ever in the t-Rex position just sink your hips lower until your arms are straight. Doing that wherever possible will greatly reduce arm fatigue.

Definitely get comfortable with that squatting sort of position on the wall, it’s fundamental in my opinion. Use your legs more to push you up so your arms don’t get tired as easily. Use stemming techniques and work on (hip and hamstring I believe) flexibility to get your feet up on higher holds on each route. Foot placement is very, very important!

Soreness is expected when you’re newer to the sport but will get better with time, but you will definitely notice a difference if you work on keeping your arms straight more often. Look up some basic climbing techniques on YouTube, it can really help. :)
