The dumbbell seated one arm bicep curl on an exercise ball with leg raised targets the biceps brachii of the working arm while challenging your balance and core. Sitting on a stability ball and lifting one leg turns a simple single-arm curl into a whole-body coordination drill, making it a good choice for building arm strength alongside core and balance control.
Cómo hacer el Dumbbell Seated One Arm Bicep Curl on Exercise Ball with Leg Raised
- 1Sit upright on the exercise ball with your feet flat on the floor, holding a single dumbbell in one hand with a supinated (palm-up) grip.
- 2Brace your core and find a stable, balanced position on the ball with your spine tall and shoulders relaxed.
- 3Raise the leg opposite (or same side, kept consistent) to your working arm until your thigh is roughly parallel to the floor, balancing on the ball.
- 4Keep the upper arm of the working side pinned against your side, with your elbow as the only moving joint.
- 5Curl the dumbbell upward toward your shoulder by contracting the biceps, exhaling as you lift.
- 6Squeeze the biceps at the top without swinging your torso or shifting your hips on the ball.
- 7Lower the dumbbell under control back to a full stretch, inhaling on the way down.
- 8Complete all reps on one side, then lower your leg, switch the dumbbell and raised leg, and repeat on the other arm.
Consejos de técnica
- Keep your core engaged and hips level throughout the set so the ball stays steady and the work stays on the biceps.
- Move slowly and deliberately — the balance demand means a controlled tempo is safer and more effective than speed.
- Pin the working elbow against your ribs so the biceps does the lifting rather than the front shoulder.
- Start with a lighter dumbbell than you would use for a standing curl until you trust your balance on the ball.
Errores comunes
- Swinging the torso or rocking on the ball to heave the weight up, which steals tension from the biceps and risks losing balance.
- Letting the working elbow drift forward, which shifts the load onto the shoulder and shortens the range on the biceps.
- Using a dumbbell that is too heavy, forcing you to drop your raised leg or brace your feet and defeating the balance challenge.
- Cutting the lowering phase short instead of extending the arm fully, reducing the stretch and overall muscle work.
Preguntas frecuentes
What muscles does this exercise work?
It primarily works the biceps brachii of the working arm. Because you sit on an exercise ball with one leg raised, your core and stabilizing muscles also work hard to keep you balanced.
Why curl on an exercise ball with a leg raised?
Removing the stable base of a bench and lifting one leg forces your core to stabilize the whole movement. You build biceps strength while also training balance and trunk control in one exercise.
Is this exercise good for beginners?
It can be, but master a standing or seated dumbbell curl first. Begin with a light dumbbell and practice balancing on the ball before adding the leg raise, then progress as your stability improves.
How many sets and reps should I do?
Two to three sets of 10–15 controlled reps per arm is a sensible range. The balance demand favors lighter weight and higher control over heavy loading.
What is a good alternative if I do not have an exercise ball?
A standard seated or standing one-arm dumbbell curl trains the same biceps. You lose the balance challenge, so add a single-leg stance to keep some of the stability work.
