and develops the biceps muscles, which are
located on the front of your upper arms and
are primarily responsible for bending your
elbows, as well as the brachialis and
brachioradialis.

your chest, tighten your abdominals and
maintain a very slight arch in your lower
back.
Motion:
• Curl handles forward, then upward, and
then in toward shoulders while keeping your
elbows at your sides and your upper arms
completely still.

performing the same arcing motion.
