In order to be successful in your physical fitness goals, you must enjoy what you are doing. Few activities are more fun, and more effective for cardio conditioning, than going a few rounds on the old heavy bag! You don't need to sign up for a boxing gym. Many commercial fitness centers have a bag or two off in the corner, or you can often find a used bag at a second hand sporting goods store.
Too many people have the idea that you have to be a boxer in order to work a heavy bag. Nonsense! Punching a bag that does not hit back is not rocket science. Here is an excellent link where you can learn everything you need to know in order to get a good workout and not feel silly doing it: http://www.rosstraining.com/forum/viewtopic.php?f=7&t=5
The one thing that is extremely important is that you MUST protect your hands properly! Hand wraps are cheap and the above link has instructions for their use. Additionally, proper gloves can be had for under $30. Personally, I use mixed martial arts gloves because they allow me to use my hands between rounds.
So, wrap your hands, wear your gloves and learn to throw a few basic punches. Now you are ready to work the bag! Try going 3-4 rounds of 3:00 with 1:00 rest between each. You'll love the stress relief and the workout!
