I have a question about weight gain. I went to the gym yesterday and checked in at 149lbs. I worked out for an hour and I did my bicep, tricep and shoulders. I did some abs as well and 8 minutes of cardio. I was drinking a small bottle of poland spring water. When I finished my workout my weight was 151lbs. Is this water gain or muscle gain or a combo? This is not the first time I have gained weight after a workout so I am just wonder what is happening.
