The barbell curl is a pure biceps mass builder. No question about it. This
exercise is considered a compound exercise that uses the biceps as the primary
mover and the front shoulders and forearms as secondary muscle groups.
This is very simple exercise to perform but as with all other exercises, form
is very important. To get the most from this exercise, you must learn to use
your biceps to move the weight. Alot of trainers rely on body momentum and
that's not how to do it. Learn how to use your biceps to move the weight
without using your body weight and you'll start to build well shaped biceps.
Remember to keep your back straight and your head level when you are doing
this exercise. Try and keep constant tension on your biceps.

thighs.
Execution of the standing barbell curl
