Sounds like you're on the right track. Weight selection is very important, especially when you're new to the program.
My best advice is to keep the weights low until you're 100% comfortable with the proper form and lifting technique. Your instructor should be giving cues in every track to help keep the workout safe and effective, pay attention to what they are saying, and be sure you understand it. If you have any questions, run up after class and ask! I always love the opportunity to explain something to a participant in detail when they have asked the question, that way they actually listen to what I have to say!
Anyways, once you have the moves down pat (this could take 5 or maybe 10 classes to really get it), start to gradually increase weight until you reach your "fitness threshold." What you should be looking for is near exhaustion by the end of the track. Yes, you're going to feel it, and yes, you may be sore the next day.
In other words:
1. if you were not able to finish the track with the weight you selected, that's a sure sign your weight is too high at that time
2. If you finish the track without even breaking a sweat, and you didn't struggle at all to finish, it is likely your weight is too light
3. If you find yourself fighting to finish, but you made it to the end, then congrats you found a weight that fits your fitness level, and will challenge you to become better!
Play around with the weights and try to find that balance with every muscle group. Remember what weight you used and how it made you feel. Keep notes even if that helps, I did!
Once you find those target weight selections, stick with them for at least a few weeks, maybe a month or two, until you feel like you're ready to try that one extra 1K plate. At that time, re-evaluate yourself, and go from there!
Congrats on making one of the most beneficial fitness decisions in your life! Stick with it, and Turn It Up!!
