FOREARM DAY WITH @Fat Gripz 💪🏻 If you want bigger forearms, you have to build the extensors, responsible for wrist extension, the flexors, responsible for wrist flexion, the Supinator and pronator, responsible for supination and pronation and the brachioradialis, responsible for elbow flexion. Let me show you how to build these muscles. A tip to increase forearm activation is to use a thicker grip by attaching @fatgripz Barbell Wrist Curls - 3x12 DB Hammer Curls - 2x12 DB Wrist Extensions - 3x12 DB Wrist Rotations - 2x15 #biggerforearms #fatgripz #forearms #forearmworkout #forearmsworkout
