anyone use punching bags for cardio?

I just got me a new 100lb everlast bag and hung it today, its been awhile for me also i took karate for 9 years and used to work on the heavy bag everyday and never get tired, things have changed lol.

I started doing this about a month ago, I'd wrap up my knuckles ina small layer of paper towels and wail on the bag for a bit to condition my knuckles and strengthen my wrists. I'd also do some light to medium punching of a concrete wall with my bare knuckes to take some feeling away and callous them up.

I have a 100# bag in my basement... It a great workout... I do 8,3min rounds with 1min break per round... Buy wraps and gloves...btw, I had to move my bag to the steel center beam in the house to reduce the noise and shock transfer...
