Cardio-Vascular training is one thing, but EFFECTIVE Cardio-Vascular training is a completely different story. If you only have 20 mins to spare and you want a workout that will not only burn fat but also increase your overall fitness (which will help you lift MORE weight) and be a real mental challenge as well, the beep test is a great training tool.

Set your distance between shuttles (20m), hit play on your CD player and you are off!
I used the beep test last year with my contest prep (that and standard high intensity cardio) and I have never looked better
