Train specifically for strength

Upon hearing this, many bodybuilders lodge a protest that goes something like this:" How can strength and size be related when i know guys who can lift heavier weights than others who are more massively developed?" The mistake here is in attempting to draw a meaningful comparison between two different individuals. The fact is that the guy with less muscle will grow larger muscles only as he grows stronger,and likewise, the more massive guy will be even larger only when he is stronger.The "apparently" greater strength of the less heavily muscled individual can be accounted for by the presence of mitigating factors such as favourable tendon attachment and superior neuromuscular efficiency. The muscles of the more heavily developed individual,while capable of contracting with greater force, have less demonstrable strength owing to the presence of such disadvantages as longer bones and the fact that, as muscles grow progressively larger, their "angle of pull" becomes less efficient.

Don't make the mistake of comparing yourself to others. The only person you can accurately compare yourself to is.. YOU! You will be bigger only when you are stronger, and so long as you are getting stronger as a result of each workout, your training is headed in the right direction.
