What Is The Best Cardiovascular Workout?

Unfortunately, there is no magical cardiovascular machine that is going to give you instant results. So which machine should you choose the next time in the gym? My first choices are the airdynne bike and treadmill.

However, the type of machine you choose doesn't really matter. What matters is the intensity that you work out at. This is a better indicator of how hard your working. So regardless of the machine you choose, increase your speed, level, or incline next time you workout. 

The least effective machines in the gym are probably the elliptical and recumbent bike. These are usually the one's being used most frequently.
