A: When doing strength training, we often only focus on lifting the weight of barbells, dumbbells or equipment, while ignoring the balanced development of the body. Over time, the body will develop asymmetrically. Everyone's left and right bodies are asymmetrical, often with great strength and good coordination. When you train your chest muscles (especially using barbells), the stronger side will bear more weight, and this imbalance will be further aggravated. If you want to improve the current problems, you should pay attention to the balance between left and right when doing any training from now on. Don't just think about lifting weights, but also pay attention to lifting weights. You can use the mirror in the gym, or ask your training partner to watch it for you, or you can watch it yourself. This correction time will not be short-term, because your muscles are used to the previous trajectory. However, after serious and certain changes, the imbalance problem will eventually be solved.
