The most important aspect of gaining mass is to have the right workout methodology. There is a science to gaining mass. The more you push your muscles the more they will be stimulated to grow bigger so that they are able to manage the strain. The most important thing to do is to lift heavy weights. You might do 8 reps with a heavier weight only but it would be much more effective than say doing 16 reps with a lighter weight.

The next thing is to choose the right equipments to workout. If you are seriously thinking of gaining weight then there is no point in working out on machines that indirectly support your body. It is best if you use dumbbells, curling rods and benches. These equipments work on every muscle in the body. Last but not the least, you will have to eat a healthy diet to support your workout.
