Is shadow boxing good exercise?

would it strengthen my arms.. chest.. or punching power in any way?|||shadow boxing is for your technique it is not a cardio excercise at all, if you want to do something that will strengthen your arms, chest punch a speed bag or a punching bag with speed and power that will make you gain muscle in those areas.|||I will do nothing for power or strength. Jimmy is totaly right. Shadow boxing is arobic that refines your combos. Its a good thing even doing it slow. After you get home from training- close your eyes and go through your combos visulize where there hitting your opponent. Reapet- repeat-repeat. Your combos should be second nature and this a great way to build that when you cant be at the gym.|||Shadow boxing is for cardio and to practice technique..Punching the bag and push-ups will give you power|||i would say so... don%26#039;t know about strength, but good for working up a sweat.
