When was the last time you threw a punch? I'm hoping that you were not punching someone on the throat.
Well, you don't have to punch anyone. Simply punching the air can offer numerous benefits. For one, punching engages your shoulders, triceps, abs, and traps.
This punching cardio workout will make you leaner and stronger in a very short period. In less than 10 minutes, you will be sweating and feeling energized.
Do this workout once or twice a day to transform your body rapidly.
