Thank you, brother!

There are often cases, not only among beginners but also among intermediate and advanced practitioners, where they try to exert more strength with the arm they primarily use, resulting in an imbalance. It's important to consciously apply equal strength to both sides and maintain proper posture. If there is a physical imbalance (and everyone has some degree of it), you need to find the appropriate balance for yourself.

It could be due to an imbalance, differences in shoulder height or protrusion, or improper posture. Try recording yourself with your phone.
