*Squats and other core exercises WILL indeed have a great impact on overall musculature and will, in fact, help build other muscle, ie. arms from squats.

cool. the more you read on about the anotomy of the body and how muscles respond to intense stress, the more you will realized exercises like the bicep curl and tricep extension are a waste of time. the general theme will ALWAYS be:

Adding more weight to the bar (or more reps, progressive load is the key) and moving as much weight as possible over the greatest ROM possible. squats and deadlifts are the two most effective ways of doing this, with the overhead press and bench pree a distant 3rd.
