Thread: Should I have my postworkout shake and carbs before cardio or after?

You should wait until immediately after the cardio is over to consume your protein and fast carbs. This is especially true for the carbs, which would blunt fat burning during the cardio workout. Don't be worried about missing your post-workout window . . . as long as you prepared properly with a pre-workout protein shake.

The pre-workout protein shake provides energy during the workout and also serves as a post-workout protein source to stimulate muscle protein synthesis.
