One of the most challenging muscle groups to build is the area between your shoulder blades.

Cable rows build stronger rhomboids and trapezius but only if you actually engage the muscles properly.

The most common back training error I observe all over the world is lack of adequate focus on bringing the shoulder blades in to meet.

Instead, mostly shoulders and biceps are engaged to lift or pull the weight.

When you train your back to gain more muscle definition it's critical to be aware of cheating like leaning backwards and then 'catch' the weight.

This technique is great for eccentric loading, but it is not always safe and since cheating into doing only eccentric repetitions is easier than concentric lifting, now you're not building quality in your sets anyway!

Check your ego if you notice that your midback is underdeveloped based on how long you've been training your back regularly.
