How fast can you punch a speed bag? How many punches can you throw in three minutes? If you want to improve your speed bag routine, you need to measure your performance. For the first time, you can track your speed bag performance directly from your device without any additional hardware. Just place your iPhone or iPad near your speed bag, press record, and it listens for your punches and gives you instant feedback.
