Cybex Bicep Curl

When doing a seated bicep curl with a Cybex machine, the biceps brachii, brachialis, and brachioradioalis are all involved.

The biceps brachii also known as the bicep muscle is a two headed muscle and is responsible for flexing and supinating the forearm at the elbow.  The brachialis is a large muscle that lies below the biceps brachii and assists the biceps brachii.  The brachioradialis is a forearm muscle that flexes at the elbow and is also capable of pronating and supinating.  Unlike other muscles found on the front of the human body, the biceps are responsible for the pulling movements.

Performing the bicep curl can make it easier when picking up an object, bringing food to the mouth, turning a key in a lock, starting your car or pulling or inserting a cork into a bottle.  Boxing, climbing, canoeing and rowing are examples of sports that utilize this muscle. Strong biceps also reduce the potential for injuries like tendonitis of the elbow, and bicipital tendonitis of the shoulder.

Instructions for the movement:

  • Adjust seat so arms are resting straight on pad (for most the seat height will be a 1-2)
  • Elbows need to align with the axis
  • Sit tall in the seat with feet flat on the floor
  • With palms up, grab handles, being sure to keep the wrist straight
  • Exhale as you bend you elbows to just past 90°
  • Inhale as you lower the arms with a soft elbow
  • Repeat with desired repetitions and sets

Be sure to keep shoulders back and down. Do not allow shoulders to round forward in order to make the lift.
