Exercise 3664 · REF X6ytgYZ
Stacking a rear-delt fly on top of a side plank turns a shoulder isolation move into a full anti-rotation core exercise — the obliques and hips have to hold the plank steady while one arm swings a dumbbell out to the side. It's a combination move better suited to conditioning or accessory work than to loading the rear delts heavy on their own.
How to Do the Dumbbell Side Plank With Rear Fly
- Start by lying on your side with your legs extended and stacked on top of each other.
- Place your forearm on the ground directly below your shoulder, keeping your elbow bent at a 90-degree angle.
- Hold a dumbbell in your top hand, with your arm extended straight down towards the ground.
- Engage your core and lift your hips off the ground, creating a straight line from your head to your heels.
- While maintaining the side plank position, lift the dumbbell up towards the ceiling, squeezing your shoulder blades together.
- Lower the dumbbell back down to the starting position.
- Repeat for the desired number of repetitions, then switch sides.
