Quick carbs are important. I make the following shake:
Soy, cow's, goat or almond milk (approx 1.5 cups) Make sure you have carbs here (e.g., not unsweetened)
Scoop of protein powder (for muscle recovery)
Tablespoon of flax oil
Blend in blender. If you use MetRx protein powder, it gets really frothy, like a shake.
