These two amazing side plank variations target your obliques and improve not only your shoulder but also HIP stability. They truly are a killer full core move! While the Side Plank Adductor Lift, works your inner thighs more, the Side Plank Abduction Raise works your glutes, specifically your glute medius, more. Give both these moves a try and if you need to modify, try using a bench to create an incline, putting your elbow up on the bench to reduce the resistance. | Redefining Strength
