I think many people forget how important pre is and only concentrate on post.
Depends on the person, I use MCTs instead of carbs and get more out of them. Granted, I don't get the pump that carbs can give but my PRs and body recomp have me caring less about the pumps. Post workout though carbs are definitely a must in almost all cases.
what about for people like me who are working out in the evenings..carbs still a good idea,even just post WO, when it's 2-3 hours before bed and you like to keep more of a shredded body type -- i.e. not a bulker.
You can take in carbs a couple hours away from sleep..
