Description
This exercise combines a side plank with a rear fly movement, targeting your core and upper body simultaneously.
How to Do Dumbbell Side Plank with Rear Fly
- 1Setup
Lie on your side, supporting your body on your forearm directly under your shoulder and stacking your feet. Keep your body in a straight line from head to heels, engaging your core.
- 2Setup
Hold a dumbbell in your top hand, letting it hang straight down towards the floor with your palm facing your body.
- 3
Engage your obliques and glutes to maintain a stable side plank position, preventing your hips from dropping.
- 4
Slowly raise the dumbbell out to the side in an arc, squeezing your shoulder blade and keeping a slight bend in your elbow, until your arm is roughly parallel to the floor.
- 5
Control the movement as you slowly lower the dumbbell back to the starting position, resisting gravity throughout the descent.
Tips
- Maintain Core Stability: Focus on keeping your hips high and your core tight throughout the entire movement to prevent sagging and maximize oblique engagement.
- Controlled Movement: Avoid using momentum to swing the dumbbell; the movement should be slow and controlled, emphasizing muscle engagement over speed.
- Shoulder Blade Squeeze: Initiate the fly movement by thinking about squeezing your shoulder blades together, rather than just lifting the arm, to better target the rear deltoids and upper back.
Common Mistakes
- ×Sagging Hips: Allowing your hips to drop towards the floor reduces core engagement; actively push your hips up and forward to maintain a straight line from head to heels.
- ×Using Momentum: Swinging the dumbbell up quickly relies on momentum rather than muscle; perform the fly slowly and deliberately to isolate the target muscles.
- ×Arching Back: Arching your lower back during the plank puts undue stress on your spine; keep your core braced and glutes squeezed to maintain a neutral spine.
