Not really... Some say it can be useful to prevent catabolism in your legs during long LISS cardio sessions... But, if you're not losing much muscle in your legs, you don't need to think about it...Well, I’m actually cutting right now. Most of my carbs end up around my workout regardless because I’m basically IF’ing. I tend to get all of my meals in before 6PM.
EDIT: Is there any point to an intra shake on cardio days?
