Well....I know you didn't ask what is the first thing I drink, but I usually drink right after I work out. The first thing I drink is MILK. I like the protein and it doesn't take long to pour into a cup.
They've developed "Recovery" drinks for after a workout, and have included various elements to help build muscles and recover lost elements during the workout. Interestingly enough, many of those elements are in chocolate milk, which is what I now use after a workout.
Often, I'll toss in a couple of bananas into a blender of skim and chocolate milk, works wonders!
If I just got back from a long run (or a cardio workout) I drink chocolate milk and usually have a banana.
However, I usually don't do cardio workouts alone. I mix everything together because that just feels like I worked my entire body by the end. After a workout like that I usually have something high in protein, like a babybel cheese or a greek yogurt with a fruit smoothie.
