Performing the: A Step-by-Step Tutorial Dumbbell Side Plank with Rear Fly
Ensure your body forms a straight line from your head to your feet, and engage your core to maintain this position throughout the exercise.
With the dumbbell in your right hand, slowly lift your arm in a rear fly motion, extending it straight out to your side until it's parallel with the floor.
Hold the position for a second, then slowly lower your right arm back down to the initial position.
Repeat the exercise for the desired number of repetitions, then switch to your right side and perform the same movements with your left arm.
