About two or three days a week after I lift, I try to do about 30 minutes of moderate intensity cardio. I know that taking a post-workout shake directly after your workout is important to boost insulin, add protein, etc. Should I take the shake between lifting and cardio, or after I'm totally done? By the way, I'm biking, so getting nauseated from eating and then physical activity isn't really a concern (that's more of a problem with running, I think).
