Make sure you are getting enough proteins in your diet. You need about one gram of protein for each pound of body weight every day. If you cannot eat enough meat, think about drinking a supplement such as soy milk or even taking a powder supplement. Eating more proteins than you need will not help you build muscles faster.
It is important for you to wait to do any cardio workout until after you have lifted weights if you are trying to build muscle.
