When is the best time of day to do cardio, and why? Well, I bet most people do cardio “whenever they get a chance.” Sometimes during the middle of the day, sometimes before bed, sometimes directly after your weightlifting workout, sometimes directly before the weightlifting workout and sometimes first thing in the morning. The truth is, all of those times will get results. It doesn’t matter what time of day you do your cardio workout, you will be burning calories every time. BUT, the real question is, which of those times is the most effective? And the answer is (drum roll please)…. first thing in the morning!
Doing cardio first thing in the morning, on an empty stomach, before you eat anything, is by far, the most effective. Whether you run, jog, walk, swim, jump rope, take an aerobics class, ride a bike, etc., doing it first thing in the morning is the best time to do it for maximum fat loss. Why? Its simple. When you do your cardio workout, you are burning calories. Lets say you wake up, eat breakfast, eat lunch later in the day, and then a few hours after lunch, you do your cardio. All you will be doing during that cardio is burning the calories and carbs of the food you just ate. When you do cardio first thing in the morning, you haven’t eaten anything for the last 8 or so hours because you were sleeping. So, when your body sees that there are no carbs to burn, it goes directly to stored bodyfat. And stored bodyfat is the fat that is on your body, which is the fat that you want to lose!
Understand how it works? When you do your cardio sometime during the day other then first thing in the morning, you spend most of that time burning off carbs that you already ate that day. When you do it first thing in the morning, there are no carbs to burn, so all your body can burn is body fat!
Some people have e-mailed me asking what type of cardio I do and I tell them I jog on my treadmill first thing in the morning. Even though I do all of my weightlifting at a gym, I do my cardio in my house on my own treadmill so I can do it first thing in the morning without having to take a shower, get dressed and do whatever else I’d do if I went to the gym to do cardio.
