After being lazy for a while, I have finally started to get back into the groove of working out again. For my cardio, I am walking on my treadmill. I usually walk on my treadmill for around 40 minutes. The problem is that I get bored after 20 minutes or so. My question is, would it be bad to split up my workouts into 2 20 minute sessions? I thought I read somewhere that your body doesn't start burning fat until after 20 minutes or so of working out, but I can't remember. Thanks in advance for your help.![]()
