Instructions
Barbell Curl
Stand up with your torso upright while holding a barbell at a shoulder-width grip. The palm of your hands should be facing forward and the elbows should be close to the torso. This will be your starting position.
While holding the upper arms stationary, curl the weights forward while contracting the biceps as you breathe out. Tip: Only the forearms should move.
Continue the movement until your biceps are fully contracted and the bar is at shoulder level. Hold the contracted position for a second and squeeze the biceps hard.
Slowly begin to bring the bar back to starting position as your breathe in.
Repeat for the recommended amount of repetitions.
Two-Arm Dumbbell Preacher Curl
Grab a dumbbell with each arm and place the upper arms on top of the preacher bench or the incline bench. The dumbbell should be held at shoulder length. This will be your starting position.
As you breathe in, slowly lower the dumbbells until your upper arm is extended and the biceps is fully stretched.
As you exhale, use the biceps to curl the weights up until your biceps is fully contracted and the dumbbells are at shoulder height.
Squeeze the biceps hard for a second at the contracted position and repeat for the recommended amount of repetitions.
