Like most competitive full contact fighting sports, muay Thai has a heavy focus on body conditioning.Muay Thai is specifically designed to promote the level of fitness and toughness
required for ring competition. Training regimens include many staples of combat sport conditioning such as running, shadowboxing, rope jumping, body weight resistance exercises, medicine
ball exercises, abdominal exercises, and in some cases weight training. Thai boxers rely heavily on kicks utilizing the shin bone. As such, practitioners of muay Thai will repeatedly hit
a dense heavy bag with their shins, conditioning it, hardening the bone through a process called cortical remodeling.
