Most people just curl… without knowing what they’re training. Your biceps have two parts — the long head that builds the outer peak, and the short head that gives width and fullness. Change your arm angle, and you change which head grows. Master both — and you’ll build complete, balanced biceps. 🧠💪 #synermuscle #bicepsworkout #muscleanatomy #longhead #shorthead #bicep #mindmuscleconnection #fitnesseducation #bodymechanics #trainingscience #armday #strengthtraining #strength #explore | SynerMus

Dumbbell Bicep Curl Variations (KNOW THE DIFFERENCE!) If you use a supinated grip to perform bicep curls, you'll primarily work your biceps. If you use a neutral grip, you'll shift the emphasis to the brachialis and brachioradialis; you'll still be working your biceps but to a lesser extent. If you use a pronated grip, you'll shift even more workload to the brachioradialis and even less workload to the biceps. Size & Shred Training program 👉🏻 deltabolic.com | Andrew Kwong
