Arm curl machine

The arm curl machine focuses on your biceps. Be careful if you’ve had elbow injuries.

Getting set
Adjust the seat so when you sit down and extend your arms straight out,
your arms are level with your shoulders and your elbows are lined up with the moving hinge or pulley of the machine. Sit down and grasp a handle in each hand with an underhand grip. See photo A in Figure

The exercise
Bend your elbows and pull the handles until they’re just above your shoulders (see photo B ), and then slowly lower the handles back down.

Do’s and don’ts

• DO make sure that you set the seat height correctly. If you set the seat too low, you’ll have trouble bending your arms and may place too much strain on your elbows.
• DO sit up tall and make an effort to pull exclusively with your arms as opposed to hunching up your shoulders or leaning back.
  
• DON’T use a chest pad to help haul the weight. If there’s a pad, use it for light support only.

Other options
Some gyms have arm curl machines that do a fair job of mimicking dumbbell work: The two sides aren’t connected so each arm has to do the work of lifting the weight. This type of machine is a good substitute or supplement for free weight work.
