Spurred on by my son's lovely comments about my man-boobs I'm going to the gym regularly again. I'm trying to lose some fat and also improve my cardiovascular fitness. On most of the machines (treadmill, cross-trainer, bikes) at the gym you can choose cardio or fat burn, the difference being how high the machine tries to hold your heart rate. Today I did 20 minutes on the treadmill and started on fat burn, because I know I can't do 20 minutes of cardio. But fat burn felt ridiculously easy, so after 10 minutes I changed to cardio.

So my question is, should I split my session like this and, if so, which should I do first? And if not should I spend a session on cardio and then a session on fat burn or just focus completely on cardio and let the weight loss come with that?
