The trainer I hired said that if you do more reps you'll get more sore. So far she is right.
If you are female, you're not going to get big no matter how heavy you lift. I recommend hiring someone to show you how to use the barbells. It's way more fun. These are the lifts that my trainer taught me:
Squats
Single leg squats (back lunge squats)
Bench press
Military press
Romanian deadlift
Discussed regular deadlift and clean and jerk but I didn't actually do them
Additionally I do some other things:
Dumbbell rows
Planks
Assisted pullups
Cable wood chops
Bridges using a stability ball
