Biceps Don't Grow in size? You're Probably Doing THIS Wrong!

Most people curl the same weight, the same way, for months — and wonder why their biceps never grow. The truth? The bicep isn't one muscle. It's three distinct targets, and if you're only training one of them, you're leaving serious size on the table. In this video, Mighty Monkey breaks down the anatomy of the bicep — the short head, the long head, and the often-overlooked brachialis — and shows you exactly which exercises hit each target for maximum growth. From preacher curls and incline dumbbell curls to Bayesian cable curls and hammer curls, every movement has a purpose and a reason. No guesswork. No wasted sets. Just a smarter way to train arms that actually builds the size and peak you've been chasing. If your bicep progress has stalled, this video tells you exactly why — and what to do next session to fix it. #MightyMonkey #BicepWorkout #ArmDay #HowToBuildBiceps #FitnessForBeginners
