should you work out on a empty stomach?

I get off at work at 3pm, should I eat prior to working out?

What kind of workout are you going to be doing?  I'd say it depends. If you doing general cardio/weights, and you've eaten through out the day (at least breakfast and lunch), you should be fine. If you your doing high intensity workouts for 1 hour +, you may need some fuel.

 I have been doing high intensity workouts and my weight seem to not budge. I didn't know if I should eat more calories or workout before I eat

how do you feel?  are you "bonking" or running out of energy during your workouts and find you can't complete them?  are you working out for more than an hour and a half at a time?  if so, you may want to consider nutrition before and/or after your workout.  i would caution to look at your nutrition plan holistically and not just around your workouts.

If your workout is an hour or less, then I'd say no. You should be able to do that on water alone as your body can pull from your glycogen stores if it needs more.

Once you get into 90+ minute workouts, then you need to worry more about fueling before, during and prior.

The only exception is, if you are hungry before a workout. You shouldn't really start a workout hungry.

 My trainer told me to have a small snack two hours before I do spin three times a week, and interval traing with weights the other three. I am six years out of surgery!I gained back 28 pounds just issues came in my life and I just got depressed feel back down wrong track. Then I started working back out not seeing any results the gym I belong to offers a free assestment with trainer. So I went and found out not eating enough calories I"ve been doing the same routine almost a month no weight lost but amazing inches coming off and muscles I've never seen before. Good luck
