A cross trainer machine is my choise. I dont believe in low intensity training (fat loss heart rate 110 to 120 beats per minute). To me dieting is all about burning calories and that is most effective with a higher heart rate. Swimming, threadmill, etc just does not do it for me. A cross trainer machine puts your arms as well as lets to work and pumps up your heart rate.

In my opinion a clever choise is to do cardio 15 minutes prior and 15 minutes after the workout. It is important to get your heart rate up before lifting weights. This will keep your heart rate higher during the work out and you will burn more calories.

At the moment I am 200lbs and I work out 6 times per week. Before lifting weights I do 15 minutes cardio with 140 to 150 bpm. During my work out my heart goes between 120 and 160. After the workout I do 15 minutes of cardio just like before the work out.

This routine allows me easily to burn +800 kcal per workout.
