@WillowWands are you generally fit or haven't you done any sport for a long time? I was a complete novice when I started lifting with Caroline but was very fit cardiowise as a runner so started with her Iron program on YouTube. She now has an Ultimate Beginner programme on the CGX app which is really where absolute beginners should start as Caroline explains all the lifts and techniques, it probably is worth the investment (£9.99 a month?)
I started it's weights of 4kg, 5kg, 7,5kg and 10kg
@Stumpedasatree I increased from 12,5kg to 15kg but need wrist straps for 3 sets of lunges with 15kg. Going to 17kg from 12,5kg is a big jump even for legs
