I'm thinking of adding some extra arm exercises at night (nothing too crazy, just some more pec/triceps to help my arms) as well as my normal routine in the mornings which I have a protein shake with water after- my question is would having a second shake after the evening workout aid my recovery time or would it just hurt my weight loss? I wouldn't want to overwork the same muscle groups twice a day but if I used other muscles in the morning workout that would be ok right?
