How to Actually Grow Your Forearms At Home Every pull-up, row, and deadlift relies on your forearms to hold the bar. If your grip fails first, your back never gets fully trained. Forearms don’t grow from random exercises. They grow when you train their four real functions: elbow flexion, wrist flexion & extension, pronation & supination, and grip strength. In this video, I show you 5 simple exercises that instantly improve grip strength and forearm size. If your hands fail before your back burns, this is why you’re stuck. Stop letting your forearms limit your gains. #forearms #forearmexercises #forearmworkout
