I’ve dabbled with both adjustable and fixed sets, and for a beginner who’s primarily focused on convenience and space, adjustable dumbbells have been a lifesaver. They let you progress without needing an entire rack of weights, and if you pick a reputable brand—like PowerBlock or Bowflex—they tend to hold up pretty well. That said, if you eventually lean towards heavier lifting and more frequent use, you might consider a fixed set for the extra durability and quicker transitions between weights. Either way, start with what feels best for your routine and space, and you can always build from there!
