Chin-ups will strengthen the back. Strengthening the muscles in your back will also have the effect of pulling your shoulders back and greatly improving your posture. Commonly the posture of people is compromised because of sitting too much, carrying extra weight in the chest area, carrying children or general imbalance from doing too much in the frontal plane. This slouchy posture not only looks bad but also causes shoulder problems like frozen shoulder. Increasing your strength in “pulling” movements will correct this imbalance and give you a great looking back!
Quiktrain core exercise
Since chin-ups involve so much effort doing few sets of chin-ups a week is enough to maintain a great deal of strength and tone of the upper body without a lot of time invested. It also keeps you in check about your body fat as carrying extra body fat will make it very difficult to complete this exercise. Once you get to this goal, you save a bunch of time on your workout by making it a staple and I promise, you will get better at it but it will never become easy. That is a Quiktrain exercise.
