This is normal. Everyone's left and right arm circumference and leg circumference are different, and even the arm length and leg length on both sides are slightly different. Under normal circumstances, you should be right-handed, so you use your right arm and right leg more than your left arm in your daily life. In addition, arms and legs may react differently to the same training. Under the same load, it is normal for one party to be more stimulated than the other. There is also a small gap between our coaches, as long as it does not affect your life and training. Only in the later practice can you strengthen the weaker parts freely.
