10. Dumbbell Side Plank💥
📝The Side Plank is so often thought of as a core strengthener only. But the realty is that it is a terrific scapular strengthener too.
🔥This variation with the Dumbbell above is a terrific way to train both shoulders in the same plank. Keep your arms in a straight line by stacking the shoulders over one another as best as you can.
