One way of looking at it this in terms of bang-per-buck. You could spend an hour in the gym doing laterals, three types of curls and tricep pushdowns. However, in this scenario, you've only worked perhaps 5% of your overall skeletal muscle mass. There just isn't that much potential for growth. The same workout spent -for example - squatting, chinning and overhead pressing might work 75% of your overall muscle mass.
The second option is therefore a more productive way to spend an hour's gym time and offers more potential for stimulating a large number of muscle fibres.
