The wide-grip EZ Bar curl is a good exercise for training the inner part of the biceps.
- Grasp an EZ Bar with your hands at a wider than shoulder width using an underhand grip (palms facing up).
- Your feet should be firmly on the floor, about shoulder-width apart. If you prefer, you can place one foot back. This is the starting position.
- Keeping your body fixed (do not swing!), slowly curl the weight up as far as possible.
- Squeeze the biceps, and then slowly lower the weight back to the starting position.
- Repeat for desired reps.
