Suggestions on what to eat before a workout

Jewel0124

I'm heading back to the gym this week after taking a month off from exercise. When I do workout, I find that I'm get hungry more than half way through my workout even though I've eaten breakfast. I usually have a cup of nonfat greek yogurt, 100 calorie bagel and fruit. Once I get hungry it's hard to concentrate and I find it difficult to finish my workout. Any suggestions on what I should eat before heading to the gym?
