They say that if someone has large biceps from pull ups they will suffer from a skinny weak back. This is because of what I call elbow domination which is when the mind if more focused on flexing the elbow as opposed to extending the shoulder.
That’s why I love this funky little pull up combo that involves twice as much shoulder movement as elbow flexion. In other words, your back works twice as hard as your arms.
