‘Rock the Boat’ is a simple exercise. You can use a chair for support if needed. Begin the exercise by standing with your feet shoulder-width apart, with even weight on each side.
Make sure to stand up straight with your shoulders back and head looking forward.
Raise one foot off the ground, bring your leg up and hold for about 30 seconds. Repeat this exercise with the other leg. You can choose the amount of reps that feels comfortable for you.
