Let say you had a very intense 50 minute workout. have your workout meal down, mainly carbs and protein. An hour later you got more energy again, not the same strength in the muscles you just trained obviously. But is there anything wrong with repping out some more sets on the same muscles you just trained about an hour ago? I don't mean to make it a habit but sometimes it's hard not to even though strength is down. It just feels good to go a little lighter again for let say 15 minutes. Is this detrimental to muscle development?
