This is going to depend on your reasons for doing cardio Riley. If your doing it solely for fatloss, i would use something along the lines of a bcaa drink for pre and post. But if your cardio sessions are mainly for endurance training, you want to have fast acting carbs before and durring and after, plus a good protien shake post as well.
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
