Big Mistake: to workout on empty stomach

Unfortunately this is a very common mistake that people make: exercising on an empty stomach. Whether they are dieting or just uninformed, working out with an empty stomach is never a good idea. Many people think it's alright to work out if they had their last meal 4-5 hours beforehand. But consider this:an intense workout puts a lot of strain on your body, which in turn requires extra energy to fuel it. If you don't eat anything for 3 hours or more before you exercise, your blood sugar level will drop dramatically during the exercise causing you to feel dizzy and nausea.
Sounds obvious, right? Well, as a professional trainer, I've seen clients and other individuals making this mistake time and time again. So spare yourself the agony and have a more productive workout by eating a healthy meal 2-3 hours beforehand. I mean, you wouldn't want to start your car with an empty gas tank, let alone drive it. So why would you do the same thing to your body?.
