Instructions: Grab a barbell with a over hand grip about shoulder width apart. Stand erect with your back
straight and your feet placed about shoulder width apart. Place your arms straight down placing
the bar slightly against your thighs. Use your forearms to
curl the weight upward in a semicircular arc up to your chest. Then reverse the movement
and slowly return the weight back down and repeat.
Don't jerk the weight up. Use a slow controlled movement. Don't lean your torso forwards
or backwards while performing the movement. Keep your back erect throughout the entire exercise.
