How do I know what weight I should be using? It's really important that you get a grasp on where you're at with your strength as quickly as possible so that you can ensure that you're using the right weights for your workouts. A good way to do this is to implement 2-3 build up sets before your working sets to get to the weight that is most suitable for you at that time.
A few important things to note with the rep ranges set in your workout plan. First, you will see a combination of both strength and hypertrophy based rep ranges. A general rule of thumb is that if you're operating in the strength rep ranges you want to be aiming for 80% + of your 1 rep max and ensuring you get 2-3 minutes rest between sets. For hypertrophy you want to be aiming for 65-75% of your 1 rep max and ensuring you get approx 90-120s rest between sets. Here's a more detailed breakdown of weight to use depending on the rep range:
STRENGTH:
3 - aim to use 90% of your 1 rep max
4-5 - aim to use 85% of your 1 rep max
6-7 - aim to use 80% of your 1 rep max
HYPERTROPHY:
8-9 - aim to use 65-75% of your 1 rep max
10-12 - aim to use 60-65% of your 1 rep max
