It depends on what your purpose is. If it's just for fitness activities, it's natural to punch and kick casually. If it is for the purpose of learning martial arts, it is useless to fight boxing at will, which is a waste of time.

Even with the purpose of fitness, we should plan regularly, practice regularly and quantitatively every day, and stick to it for a long time, otherwise it will be ineffective.

There are many factors that determine the outcome of the attack, not to mention objective conditions, mainly the confrontation between the two sides' physical conditions, technical conditions and willpower. When the difference between physical conditions and technical conditions is too great, willpower will not play much role. Physical conditions include physical quality, strength, speed, reaction ability, coordination ability and so on. Technical conditions mainly refer to the reasonable mastery of offensive and defensive techniques. These all need a long-term systematic training and learning process, and most of the links need the specific guidance and help of experts. These technical details are summarized by predecessors through countless actual combat experiences, and can't be imagined or understood at will. You can't practice boxing alone.
