I've been doing some reading up on punching bag workouts and it seems that most people tend to tire out after about 2-3 minutes after an all-out effort. So it sounds to me that punching bags could be a good vehicle for HIIT exercises. Which is great for me because I find treadmills and stationary bikes fairly boring.
So any of you guys train with a punching bag on a regular basis? Did you notice any improvement in your upper body strength? How did it compare with your normal cardio training?
