Ground Oats or Oat Powder.
The question comes down to a few factors:
-How long before a workout you eat and what does the food consist of
-What type of workout you do
-How long you workout for
-How many times a day you workout
... All of these questions will answer whether or not you have a glycogen depletion or not. Glycogen depleting workouts would be long distance running or longer workouts (3-4 hours). My guess is that you don't do any of these on a regular basis. If this is the case, a steady insulin and glucagon flow is necessary for sustained energy, both during and post workout.
A solid meal with good fats, protein, and complex carbs should sustain insulin quite well, in addition, if insulin is never depleted, all you'll need is a complex carb post workout such as ground oats or oat powder.
