Dumbbell Split Stance Biceps Curl
- Intermediate
- Isolation
- Rep-based
- Shoulders
- Upper arms
The split stance biceps curl enhances stability and prevents momentum, allowing for better isolation of the biceps brachii. By staggering the feet, you create a more stable base that discourages lower back arching and torso swinging common in standard standing curls.

Setup
- Stand with one foot forward and the other back in a comfortable staggered stance, about 2 feet apart.
- Hold a dumbbell in each hand at your sides with a neutral grip (palms facing your body).
- Engage your core and keep your chest upright with shoulders pulled back and down.
- Distribute your weight evenly between the front and back foot to create a solid foundation.
How to do it
- Exhale as you curl the weights toward your shoulders, rotating your wrists so your palms face up at the top of the movement.
- Squeeze your biceps hard at the peak of the contraction while keeping your elbows pinned to your ribs.
- Inhale as you slowly lower the dumbbells back to the starting position over a 2-3 second count.
- Maintain a tall posture throughout the set, ensuring your torso remains completely still.
Form checklist
- Keep elbows fixed at your sides; do not let them drift forward to 'cheat' the weight up.
- Avoid leaning back or using your hips to generate momentum.
- Maintain a neutral neck and look straight ahead to keep the spine aligned.
- Ensure a full range of motion by fully extending the arms at the bottom of every rep.
Pro tips
- Focus on rotating your pinky finger toward your outer shoulder at the top of the curl to maximize the peak contraction of the biceps.
- Switch which leg is forward on every set to challenge your balance and core stabilizers evenly.
Make it harder
- Incorporate a 3-second isometric hold at the 90-degree mark (mid-point) of the curl on every repetition.
- Perform the eccentric phase even slower, taking 4-5 seconds to lower the weight from the shoulder to the hip.
