If you’re looking to build muscle at home or in the gym, you’ve probably seen many types of weights. You might be wondering, what are the round dumbbells called? Those solid, ball-shaped weights with a single handle are a classic piece of equipment.
They are known as hex dumbbells, or sometimes hexagon dumbbells. The name comes from their six-sided shape, which is their key feature. This design stops them from rolling away on the floor, unlike round ones. This makes them safer and more convenient for many exercises.
What Are The Round Dumbbells Called
To be clear, the dumbbells you’re asking about are almost always hex dumbbells. True “round” dumbbells, like the old-school iron globes, are less common in modern gyms. When most people refer to round dumbbells, they are usually picturing the hex variety. It’s a common mix-up in terminology.
Understanding the different types helps you choose the right tool. Let’s look at the main kinds you’ll encounter.
Types of Dumbbells You’ll Find
Not all dumbbells are created equal. Each type has it’s own pros and cons for your training.
- Hex Dumbbells: These are the answer to our main question. They have a hexagonal shape to prevent rolling. They are typically made of cast iron with a rubber coating. This coating protects floors and reduces noise.
- Round Rubber Dumbbells: These have a circular shape but are fully encased in rubber. They are kinder to floors but can roll. You’ll often see these in commercial gyms.
- Adjustable Dumbbells: These let you change the weight by adding or removing plates. They are space-savers but can be slower to adjust between sets.
- Selectorized Dumbbells: Brands like Bowflex offer these. You turn a dial to select the weight. They are incredibly convenient but come with a higher price tag.
Why Hex Dumbbells Are a Top Choice for Strength
Hex dumbbells are a favorite for good reason. Their design offers several advantages that directly support effective strength training.
- Safety First: The flat sides mean no rolling. This is crucial when you’re putting them down after a hard set of presses or rows. You won’t chase them across the room.
- Stable for Exercises: They sit firmly on your thighs when your positioning for a press. This makes getting them into start position much easier and safer.
- Durable Construction: Made from solid cast iron, they can withstand years of heavy use and drops. The rubber coating adds to their longevity.
- Clear Weight Markings: The weight is usually clearly marked on the head, making it easy to grab the right pair quickly.
Potential Drawbacks to Consider
While excellent, hex dumbbells have a few minor limitations. For some rolling exercises, like certain forearm work, a round dumbbell is actually preffered. Their hexagonal shape can be slightly awkward for these specific moves. Also, the rubber coating can sometimes develop a smell in humid environments, but this is rare.
How to Use Hex Dumbbells in Your Routine
Incorporating hex dumbbells into your workouts is straightforward. They are versitile and can be used for every major muscle group.
Here is a simple full-body workout you can try:
- Dumbbell Goblet Squat: Hold one dumbbell vertically against your chest. Keep your core tight as you squat down, then drive back up. Do 3 sets of 10-12 reps.
- Dumbbell Bench Press: Lie on a bench with a dumbbell in each hand. Press the weights up until your arms are straight, then lower with control. Do 3 sets of 8-10 reps.
- Bent-Over Dumbbell Rows: Hinge at your hips with a slight knee bend. Pull the dumbbells to your torso, squeezing your shoulder blades. Do 3 sets of 10-12 reps.
- Standing Dumbbell Shoulder Press: Press the dumbbells from shoulder height to overhead. Avoid arching your back. Do 3 sets of 8-10 reps.
- Dumbbell Lunges: Hold a dumbbell in each hand. Step forward and lower your back knee toward the floor. Alternate legs. Do 3 sets of 10 reps per leg.
Choosing the Right Weight for You
Selecting the correct weight is critical for progress and safety. A weight that’s to light won’t build strength, while one that’s too heavy risks injury.
Follow this basic guide:
- For Learning Form: Start very light. Your focus should be on perfect movement, not heavy weight.
- For Muscle Growth (Hypertrophy): Choose a weight that allows you to complete 8-12 reps with good form. The last 2 reps should be challenging.
- For Pure Strength: Use a heavier weight for lower reps, typically in the 4-6 range. You’ll need longer rest periods between sets.
- Progressive Overload: This is the key principle. When a weight feels to easy, gradually increase it. This is how you get stronger over time.
Caring for Your Equipment
Taking good care of your hex dumbbells ensures they last a lifetime. Wipe them down with a dry cloth after use to remove sweat. For the rubber coating, you can occasionally use a mild soap and water solution. Avoid using harsh chemicals that could degrade the rubber. Store them on a rack if possible, rather than piling them on the floor, to prevent chipping.
