Dumbbell One Arm Fly on Exercise Ball

Description

How to do Dumbbell One Arm Fly on Exercise Ball

1. 01
   Setup

   Position yourself on an exercise ball with your upper back and head supported, feet flat on the floor hip-width apart, and hips lifted to form a straight line from knees to shoulders.

2. 02
   Setup

   Hold one dumbbell in one hand with a neutral grip (palm facing in), arm extended straight up over your chest with a slight bend in the elbow. Your non-working arm can be placed on your hip for balance.

3. 03

   Inhale deeply and slowly lower the dumbbell in a wide arc out to the side until your upper arm is parallel to the floor, maintaining the slight bend in your elbow.

4. 04

   Exhale as you reverse the motion, squeezing your chest to bring the dumbbell back up over your chest in the same arc.

5. 05

   Focus on contracting your pectoralis major throughout the movement, ensuring your core remains stable and hips stay elevated on the ball.

Tips

• Maintain a slight, consistent bend in your elbow throughout the entire movement to protect the joint and maximize chest engagement, avoiding a locked-out arm.
• Lower the dumbbell slowly and with control, feeling the stretch in your chest, rather than letting gravity drop the weight quickly.
• Actively brace your abdominal muscles and glutes to keep your hips elevated and stable on the ball, preventing unwanted swaying or arching of the lower back.
• At the top of the movement, visualize and actively squeeze your chest muscles, rather than just bringing the dumbbell up, to maximize muscle activation.

Common mistakes

• Avoid lowering the dumbbell past the point where your upper arm is parallel to the floor, as this can overstretch the shoulder joint; instead, stop when you feel a good stretch in your chest.
• Do not let your hips sag or body wobble on the ball; actively engage your glutes and abs to maintain a stable, flat torso throughout the set.
• Prevent locking out or fully extending your elbow at the bottom of the movement, which puts stress on the joint; maintain a soft, slightly bent elbow throughout the entire range of motion.
