Rotational punches are an exercise that works the core and shoulders. It can be performed weighted or unweighted.
To perform this exercise, stand with your feet a little wider than shoulder width. To perform the first “punch,” rotate your torso to the right and pivot on your left foot while you extend your left hand and rotate it so that your closed palm is facing the ground. After you pull back, alternate to your other side. The idea of this exercise is to perform it slowly and controlled.
A common mistake in this exercise is to use heavyweights. It works better if you use lighter weights as it is designed to engage your core rather than build your arms.
This exercise is perfect for beginners as you can either use no or very light weights. If you want to make it harder, you can even add a squat between rotations.
