Fixed-Weight Dumbbells

Generic fixed-weight dumbbells are the most common type of dumbbells available, and you'll find them in any gym or fitness center. As their name suggests, these dumbbells are not expandable and weight can't be added or reduced. Commonly made from iron or steel, fixed-weight dumbbells are incredibly durable. Iron hex dumbbells, which are shaped like a hexagon at the ends, are popular because they don't roll around. Rubber-coated versions are available to protect your floors if the weights get dropped. Fixed-weight dumbbells also come in lighter versions coated in vinyl or neoprene to make them more comfortable to hold.

While fixed-weight dumbbells are easy to use and inexpensive if you only need a pair or two, the cost can add up quickly if you want a complete set. Weider, Cap Barbell and Body-Solid are popular manufacturers, although we found the best reviews for the Cap Barbell Cast-Iron Dumbbells (*Est. $10 and up). If you want more variety for your strength-training workout, adjustable dumbbells like the Bowflex SelectTech (*Est. $400 and up) or PowerBlock Sport Series (*Est. $150 and up) are recommended.  

Few professional sources test fixed-weight dumbbells, and they don't attract many user reviews. Buzzillions.com and Amazon.com are good sources to check, but most fixed-weight dumbbells only attract a few ratings.
