You will want a little fuel to get you through your workout but not a heavy meal that will make you feel sluggish. If your session is in the morning, a smoothie or some fruit and a bagel would be good options. If you are working out at lunchtime – you may want to eat a bit of your lunch before your class and the rest after. That way you won’t be starving and lacking energy for class but also won’t be overly stuffed and trying to crunch your stomach during class! If you are working out after work – you may need a quick snack to keep you going. Again fruit or handful of nuts could do the trick.
