Well - if you want: to become muscular - just sitting around isn't going to make it happen. If you decide to get serious about building muscle, talk to your coach or a trainer about getting you on a schedule and teaching you the right exercises.

Building muscles: Unfortunately, without working your muscles (muscles get bigger when they are "worked out" ) they won't get bigger - so the gym is the way to go or you could start at home - a gallon of water is 8 pounds so you could make your own weights - You might want to consider a protein supplement if you start to work out - most vitamin shops should carry one. The exercise should be balanced.
