What muscles are used in boxing doing the right cross?

The right cross in boxing primarily engages the muscles of the upper body, including the deltoids, pectorals, and triceps for shoulder and arm movement. The core muscles, particularly the obliques and rectus abdominis, are crucial for generating power and stability during the punch. Additionally, leg muscles, such as the quadriceps and calves, play a significant role in providing the necessary force and balance as you pivot and rotate your body. Overall, a coordinated effort from these muscle groups contributes to the effectiveness of the right cross.
