If you’ve ever wondered how to put two dumbbells together, you’re in the right place. This simple method can create a makeshift barbell or kettlebell, opening up new exercise options without needing more equipment.
It’s a clever space-saving trick for home gyms. You can combine weights for heavier lifts or for different grip positions. Let’s look at the safe and effective way to do it.
How To Put Two Dumbbells Together
This technique is straightforward, but doing it correctly is key for safety. The goal is to securely join two dumbbells so they function as a single, stable unit.
You’ll need a few simple items, most of which you probably already have at home. The process takes just a minute once you get the hang of it.
What You’ll Need
Gathering your materials before you start makes everything smoother. Here’s your checklist:
- Two dumbbells of the same weight and design (hex or round ends work best).
- A sturdy, adjustable wrench or a set of dumbbell collars/clamps.
- A roll of strong duct tape or weightlifting tape.
- An optional towel or pad for floor protection.
Step-by-Step Joining Process
Follow these steps carefully to ensure a secure connection.
Step 1: Prepare the Dumbbells
Lay both dumbbells side-by-side on the floor. Make sure the handles are parallel and the weight heads are aligned. If your dumbbells have hex heads, position them so the flat sides face each other. This creates a more stable connection point.
Step 2: Secure the Handles
This is the most important part. Bring the two handles together tightly. Wrap the duct tape around the middle of the handles multiple times. Pull the tape taut with each wrap to eliminate any slack. Overlap each pass by about half the tape’s width. Aim for 8-10 solid wraps.
For a more permanent solution, use the adjustable wrench. Place it over both handles in the middle and tighten it until it’s very snug. The wrench acts like a large, metal clamp.
Step 3: Reinforce the Connection
After taping the center, add stability by taping near the inner weight heads. Wrap tape around the handles where they meet the inner plates. This prevents the dumbbells from pivoting or wobbling during use.
Check that there is no gap between the two handles. They should feel like one thick bar.
Step 4: Final Safety Check
Before lifting, perform a simple test. Grip the combined dumbbell with both hands and gently lift it a few inches off the ground. Shake it lightly. Listen and feel for any movement or shifting. If you hear clicking or feel play, add more tape until it’s completely solid.
Best Exercises for Combined Dumbbells
Now that you’ve secured them, here are great ways to use your new piece of equipment. The double-dumbbell setup is fantastic for exercises where you want a barbell-like feel but with the convenience of dumbbells.
- Modified Barbell Rows: Hold the combined dumbbell with both hands for a stable, neutral-grip row.
- Hip Thrusts: Place the long handle across your hips (use a pad for comfort) for excellent glute work.
- Landmine Presses: Wedge one end into a corner and press the other end. The taped handle provides a secure grip.
- Goblet Squats: Hold one end of the combined dumbbell vertically against your chest. This challenges your core stability.
Important Safety Tips to Remember
Safety always comes first in fitness. Ignoring this can lead to injury or damaged equipment.
- Always inspect the tape or clamp before each use. Look for tears, stretching, or loosening.
- Start with lighter weights to test the stability of your connection method.
- Never use this method for overhead lifts like snatches or heavy clean and presses. The shear force is to great.
- Keep the combined dumbbell away from your face and head during exercises.
- Ensure your grip is even on both sides of the taped center to maintain balance.
Common Mistakes to Avoid
Even with a simple method, it’s easy to slip up. Here’s what to watch out for.
- Using Uneven Dumbbells: Combining a 25lb and a 30lb dumbbell creates an unstable, dangerous imbalance.
- Insufficient Tape: Three or four loose wraps won’t hold under load. Be generous with the tape.
- Ignoring the Inner Collars: Not taping near the inner weight heads allows for to much leverage and potential failure.
- Using Weak Tape: Flimsy masking tape or painter’s tape will rip immediately. Use heavy-duty duct tape.
Alternative Connection Methods
If tape isn’t your thing, consider these other reliable options.
- Heavy-Duty Velcro Straps: These can be wrapped tightly and are reusable.
- Actual Dumbbell Clamps: Specialty clamps designed for this purpose can be purchased online.
- Two Adjustable Wrenches: Using one on each side of the handles can provide an extremely secure, metal-to-metal lock.
FAQ Section
Can I put any two dumbbells together?
It’s best to use dumbbells of identical weight and shape. Mixing a hex dumbbell with a round one creates a poor connection surface. The handles should also be the same diameter for a even grip.
Is putting dumbbells together safe for heavy lifting?
For moderate weights, yes, if done correctly. However, this method is not designed for maximal, one-rep lift attempts. The stress on the tape or clamp is significant. Always err on the side of caution and use it for controlled, volume-focused work.
How do I take the dumbbells apart?
Simply cut the tape with scissors or a knife. If you used a wrench or clamp, just loosen and remove it. There’s usually no damage to the dumbbells themselves.
What’s the best way to combine dumbbells for a makeshift kettlebell?
To simulate a kettlebell, tape the handles together at the very end of the dumbbells, leaving one weight head free to swing. This creates a top-heavy “bell” shape. Grip the taped handles and perform swings with extreme caution, starting with very light weight.
Will this method damage my dumbbells?
Duct tape can leave a sticky residue. This can usually be cleaned off with rubbing alcohol or adhesive remover. Metal clamps or wrenches might scratch the finish on the handles, but this is purely cosmetic.
Learning how to put two dumbbells together is a useful hack for any fitness enthusiast. It expands your home gym possibilities without spending extra money. Remember, the key is a secure, wobble-free connection.
Always prioritize safety over weight. Test your setup thoroughly, and focus on controlled movements. This simple technique can effectively add variety to your strength training routine and help you work around equipment limitations.
