Which Deadlift Style Should You Choose?
Share
If you’ve ever wondered whether conventional, sumo, or hex bar deadlifts are best for your goals, you’re not alone. All three are common in strength training routines, but each activates muscles differently. A recent study looked at how these styles compare when performed with heavy loads, similar to what serious lifters use in the gym.
The 3 Main Deadlift Styles
Conventional Deadlift (CDL)
This is the classic style where your feet are hip-width apart, your grip is outside your knees, and your back is more inclined forward.
Sumo Deadlift (SDL)
In this version, your feet are wider and your hands are inside your knees. You maintain a more upright torso and open hips.
Hex Bar Deadlift (HBD)
You step inside a hexagonal bar and grip the handles at your sides. This allows a more balanced stance and upright torso, similar to a squat.
What the Study Did
Twelve experienced male lifters performed all three deadlift styles at 90 percent of their one-rep max. Researchers measured which muscles worked hardest using sensors and also tracked how much weight was lifted and how the joints moved.
Key Takeaways
1. Hex Bar Deadlifts Let You Lift More
On average, lifters could move the most weight with the hex bar. That’s likely because the grip and stance make the lift more efficient and stable.
2. Hex Bar Deadlifts Activate More Muscles
Compared to the other styles, hex bar deadlifts showed higher muscle activation in most areas, especially the back (erector spinae), glutes, and quads. This makes them ideal for full-body strength.
3. Conventional Deadlifts Target Hamstrings
If your goal is to build the hamstrings, especially the biceps femoris, the conventional deadlift came out on top. This is likely due to the more bent-over position, which puts more stretch and load on the back of the legs.
4. Sumo Deadlifts Are a Middle Ground
The sumo deadlift showed moderate muscle activation across most muscles. It had slightly more back engagement than the conventional style but less hamstring involvement. This could be a good option if you have mobility issues or want a lift with less forward lean.
What About Joint Movement?
Each style changes how your hips and knees move:
- Hex bar deadlifts had the deepest knee bend, which likely contributed to more quad use.
- Conventional deadlifts required more hip flexion, increasing hamstring activation.
- Sumo had the least hip movement but the most upright posture.
Which One Should You Use?
Use the Hex Bar Deadlift if:
- You want a full-body workout with higher muscle involvement
- You’re training for power or athleticism
- You want a safer, more upright lifting posture
Use the Conventional Deadlift if:
- You want to focus on hamstrings and posterior chain strength
- You’re preparing for powerlifting competitions
- You prefer traditional barbell movements
Use the Sumo Deadlift if:
- You want to reduce strain on your lower back
- You have longer legs or hip mobility challenges
- You want a hybrid between squat and deadlift mechanics
Final Thoughts
There’s no one best deadlift style. It depends on your body, goals, and training history. If you’re training for overall strength and muscle growth, the hex bar deadlift is a solid choice. If you want to target your hamstrings, stick with the conventional style. For a more back-friendly or mobility-friendly option, go with sumo.
Whatever you choose, focus on proper form and consistency. Your gains will come with time, effort, and smart programming.
