Back muscles are notoriously difficult to build up due to multiple reasons. The first is that you can’t see them so they are difficult to monitor as you work out. As a result, you will need someone (like a personal trainer) to tell you how your muscles are performing while you exercise. This way, you can switch exercises to target certain muscles that need a bit more work. Secondly, the back is pretty complex. There are a lot of muscles working together there and so, it’s much more difficult to stimulate back growth compared to other parts of the body like your legs or arms. But, with hard work and perseverance, you can still build your back muscles so they are stronger.
