Barbell biceps curl

The barbell biceps curl targets your biceps.
Be especially careful if you have elbow problems. Whenever you add weight and bend a joint, it increases the stress to that joint. Therefore, if you have a weakened joint, you need to exercise extreme care not to overdo it and cause an injury. If you have lower back problems, you may want to choose a seated biceps exercise instead.

Getting set
Hold a barbell with an underhand grip and your hands about shoulder-width apart. Stand with your feet as wide as your hips, and let your arms hang down so the bar is in front of your thighs (see photo A of Figure 14-2). Stand up tall with your abdominals pulled in and knees relaxed.

The exercise
Bend your arms to curl the bar almost up to your shoulders , and then slowly lower the bar almost to the starting position.
Do’s and don’ts

• DO keep your knees relaxed. This protects your lower back.
• DON’T rock back and forth or lean way back to lift the weight. If you need to do that, you should be arrested for using too much weight.
  
• DON’T just straighten your arms and let the bar drop down to your thighs like a sack of rocks. Instead, lower the bar slowly to get the most muscle power from the exercise and to protect your elbows. And don’t lower the bar all the way back down because you lose tension on the muscle.

Other options

• Reverse-grip biceps curl (harder): Do the basic version of the barbell biceps curl holding the bar with an overhand grip. You feel this exercise more in your wrists. (Hint: Use a lighter weight for this version.)
• Cable biceps curl: Place the cable on the setting closest to the floor and attach a short or long straight bar. Hold the bar with an underhand grip and stand about a foot away from the cable tower. Curl the weight up and down exactly as in the basic version of the barbell biceps curl.
• Double biceps curl: Hold a dumbbell in each hand with your palms facing up, elbows resting lightly against your sides, and arms hanging down. Curl the dumbbells up and down together as if they were a barbell.
