If I had to pick one tool to help improve my cardiovascular fitness, it would be a heart rate monitor.  It can be distracting and sometimes inaccurate to try to get a pulse rate while you are still exercising.  Heart rate monitors give you a real time heart rate with nothing more than a glance at the watch.  This helps you to monitor your intensity and ensure that you are working out in the heart rate training zone that will provide you the most benefit.

Although you can find hundreds of different models of heart rate monitors (and prices) I have found some of the more affordable ones from the Bike Nashbar site which is the link that I have provided here.

This is the best price I found in my web search.  A cheap but fairly accurate alternative to the high dollar devices that professionals use.
 

Track your body measurements and progress as your muscles grow and your unwanted fat goes away.  This handy tape measure makes it easy for you to measure yourself without needing an extra pair of hands.
