Weak Shoulders and Weak Wrists in Plank Pose Today’s question comes to us from the membership site from Donna who is finding it challenging to do plank pose because of weak shoulders and weak wrists. So first of all you can do plank pose on your forearms instead of your hands which will give your wrists a break. Secondly make sure you practice shoulder loop and staying broad across your chest in plank pose to stay strong in your shoulder girdle in plank pose. This pose will build strength in your shoulders over time. Finally you might also try building up strength in your shoulders with modified side plank.
