Just make sure you're not slacking on your prehab /rehab /warmups, especially if you're training heavy.
Oh and kinda related to this and your original post, if you're only in the gym 1hr and are doing cardio after you could just do your shake after cardio..
You'll be fine
Drinking carbs before post workout cardio kind of defeats the purpose.
I personally like to do my cardio first thing after waking, drink some bcaas and Glu, then do cardio, then home, big breakfast, and weights after that.
