Do you want to ask why boxers are all eight-pack ABS instead of fat people? The strength of boxing comes from the muscles of the lower limbs. According to Sohu news information, half of the punch impact in boxing comes from lower limb muscles such as calf gastrocnemius and quadriceps femoris, and the leg strength is transmitted to the fist through the core muscles of the trunk. As a part of the core strength source, abdominal muscles are constantly tempered in training every day, so people who fight boxing are all eight-pack abdominal muscles instead of fat people.
