While pull-ups and chin-ups are great exercises to strengthen your upper body, unfortunately, they won't directly increase your height.
Height is largely determined by genetics and can be influenced by factors such as nutrition, exercise, and sleep. Pull-ups and chin-ups can help improve your posture and increase your overall strength, which can make you appear taller and more confident. However, they will not make you physically grow taller.
To optimize your height potential, it's important to focus on factors that are within your control. Eating a balanced diet rich in essential nutrients, getting enough sleep, maintaining good posture, and engaging in regular exercise can all help promote optimal growth and development.
If you're still in your growing years, you can focus on maintaining a healthy lifestyle and engaging in regular physical activity to ensure that your body reaches its maximum height potential. However, once your growth plates fuse (usually around the age of 18-21 for most people), your height is unlikely to change significantly.
It's important to remember that height is just one aspect of overall health and well-being, and there are many other factors that contribute to a healthy and fulfilling life. Focus on maintaining a healthy lifestyle and being confident in yourself, regardless of your height
