The transverse plane, though here focusing on the shoulders, will also exercise the upper and lower half of your body, including the core. Lori uses a resistance band to demonstrate these exercises.
These movements can help create muscle definition, but they primarily focus on building and maintaining the health of the shoulder. The exercises are especially helpful for those who may be in rehab for the shoulder area.
Relieve boredom with exercises–and improve your results—by switching them up. See our other two videos for shoulders using the frontal plane and sagittal plane.
