I'm also trying to gain weight. Unfortunately, I'm so busy I seldom have time to stick to my plans for more than a couple days a month. I did start to see some results last summer after classes got out. I got into a cycle for a month of lifting 3 times a week, having at least one soccer practice and one soccer game, and squeezing in bike rides when it was convenient. Soccer doesn't do much for the upper body, but it sure builds the legs and butt. I think the riding was good because it works a slightly different set of muscles. I also try to watch what I eat. By watch I mean fill up on protein and carbs and snack on carbs between meals, while still rounding out the 5 food groups. Of course, I wasn't very scientific about it and I have no idea what by body fat sits at, but I picked up about 5 pounds in that month. Then school started again and I lost those 5 pounds in about a month.
