RE: Muscle without weight?
I take it you are aiming to increase muscle mass as a priority then (bulking)?
Do you feel you have gained no muscle what so ever in the last month?
Some people will tell you to expect a slight increase in fat when trying to add mass effectively.
If you feel you are gaining fat too fast then maybe drop your food intake slightly.
Some people like to go mad with food when bulking, others take a more conservative approach. What is acceptable fat increase for some isn't for others.
