How to Shadow Box Like a Champ

"Shadow boxing is a fundamental boxing skill. It provides an opportunity for boxers to fine-tune their technique and mentally prepare for a workout or fight.

For non-boxers, shadow boxing can be an excellent warm-up for a workout or even a workout in and of itself — you’ll be amazed at how quickly it revs up your heart rate. This low-impact cardio can be done pretty much anywhere —the gym, your garage, a hotel room. You can even shadow box in the dark after you’ve rambled in the park. (Only real ones know that reference)."
