I work out in the mornings before I eat my breakfast. I’ve never had any problems!!

This is what Jillian Michaels recently said in an interview re: working out on an empty stomach:

Jillian: Never work out on an empty stomach or you’ll lose muscle mass because your body will convert muscle into glucose. Eat about 45 minutes to 1 hour prior to working out so you have enough blood sugar. You want to be fueled, but you don’t want to get cramped because your stomach is full. Get a good combination of complex carbohydrates, healthy fat and protein. Have a handful of raw walnuts and an apple, almond butter on half an Ezekiel English muffin, or low-fat organic yogurt and organic berries.

Back in the old days, people thought they should train on an empty stomach in order to burn more fat, but that has turned out to be FALSE. In fact, your body needs some glucose (blood sugar) for fuel in addition to what it can use from fat stores when you’re working out. If you don’t have any blood sugar available, your body will eat the muscles’ glycogen, or stored glucose. Low blood sugar will also make you tired and sluggish during your training session. For these reasons, I suggest you eat something 45 minutes to an hour before training — you’ll have more energy and endurance to work harder, burn more calories, and improve your muscle tone.
After training, during a period known as the golden hour (45 to 60 minutes after a workout), muscles absorb the most nutrients, and glycogen is replaced the most efficiently. You don’t have to have a huge meal — just a little something that contains both protein and carbs will give the best results.

I always try to have something in there, like half an apple or a cup of yogurt. I really get run down and low blood sugar otherwise.

there was a post in the nyt a few weeks ago about a study that was done. 1 group ate a big breakfast, then worked out. the other group worked out, then ate a big breakfast. the 2nd group lost more weight and had better heartrates while working out.

i usually just drink a small cup of coffee then head to the gym.

I always just have coffee, and then go work out. If I’m working out later in the day, I make sure that I haven’t eaten anything for at least and hour and a half (longer if the last thing I ate was big).

For cardio – I do the same thing as some other posters – I have coffee and several glasses of water, work out, then eat breakfast.  I have a really hard time working out if there is anything in my stomach.

For yoga – I am a lot less picky about my routine, but I like to have at least an hour between a meal and yoga class – otherwise I feel kind of heavy.

@Evie19: I almost always do cardio when I work out, maybe followed by some strength training.

I try not to work out on an empty stomach, but it happens sometimes.  I’ll wake up, have some espresso, and go for a run. Then I just have a tummy-friendly breakfast when I get back home.

I’ve done weights a couple times in the morning on an empty stomach, too.  I think as long as you’re eating pretty well in general, doing this sometimes isn’t going to kill you.

I find I have my best workouts after half an English muffin at least, though, and it’s so tummy friendly it seems not to be a problem even for my sensitive system.  In that case, I usually wait 20 minutes in between eating and working out.

I’ve never had a problem working out first thing in the morning on an empty stomach. Just as long as you hydrate first, you should be fine. I actually prefer it, but I know some disagree with it.
