Total weight sets
When you get a pair of adjustable dumbbells or even just one adjustable dumbbell, you are replacing multiple sets of weights. This saves you space and money. Adjustable dumbbell sets vary in terms of how many weights they actually replace. The less weight the adjustable dumbbell has total, the fewer dumbbell sets it replaces. These lighter adjustable dumbbells can replace 15-16 sets, which is still a significant number of weights. The heaviest adjustables can replace as many as 18 sets, so you are essentially getting a full gym’s worth of weights in just two dumbbells.
Adjustable dumbbells replace multiple weights through a system of increased weight increments. By using a dial or plate system, you have control over how much weight resistance you are getting from the dumbbell. Most dumbbells go up in 5-pound increments, beginning with very little weight at 3-5 pounds. You can adjust the weight up from there to resistances of 20-50 pounds per hand, for a total of 100 pounds. More advanced adjustable dumbbells can even get as high as 100 pounds for each hand, so you would be lifting a total of 200 pounds. This is more than enough for a seasoned pro, and with such a wide range of resistances, anyone can get started with a weight-training program using adjustable dumbbells.
Handling dumbbells needs to be comfortable, or it will be hard to keep training for very long. Features like thermoplastic rubber handles provide a no-slip grip, so you can safely use the dumbbell without fear of dropping it as your hands get sweaty. Handles with padding are also beneficial because they protect your wrists.
Adjustable dumbbells are usually made of plastic, steel, or cast-iron. Plastic weights break down quickly, and are not very reliable. Dumbbells made of material like steel or cast iron are much more durable. Many adjustable dumbbells also have chrome plates or chrome handles for extra protection.
The major benefit of adjustable dumbbells is that you only need two instead of multiple sets of weights that take up a lot of space. Individual dumbbells are usually very compact and come with storage trays or stands where you can place the dumbbells when you are not using them.
