Are you particular about what you eat, pre-workout? It's always been a bit of a conundrum for me: I don't want too much in my stomach because it somehow expands to feel like it's the size of a bowling ball in there when I'm bouncing around during a workout, but I don't want to eat nothing, either, because then I'll run out of energy and either faint or give up early. So what's the answer?
Part of the answer, at least, has to do with when you eat. If you're eating a large meal, you should wait 3-4 hours before exercising; a smaller meal needs 2-3 hours to digest; and a snack needs about 30 minutes to an hour to settle in.
But what should you eat? Forget straight-up carbs; they'll burn up quickly and leave you totally energy-less, say experts. Instead, aim for a protein-carb mix: yogurt with fruit, an apple with a handful of almonds, a piece of whole-wheat toast with a smear of peanut butter.
