Nicole Hollar explains progressive overload: increase weight gradually, avoid big jumps especially with small muscles like biceps, and use drop sets or reduce reps to keep training safely without injury.
You want to progress slowly when you graduate in weight. Don't suddenly jump many, many percentages or pounds of weight at a time. If you have a bigger group, sure, jumping 10 pounds for your squat might not be a big deal, but jumping 10 pounds for your bicep curl is a huge deal because the bicep is obviously not capable of navigating and managing nearly as much weight. As the entire lower body. So you want to progress smartly and slowly, even if that means drop setting, doing fewer reps, and then lowering the weight to continue a few more.
