Grasp a barbell or Olympic bar at around shoulder width apart using areverse grip (palms facing down).

Stand straight up, feet together (you may be more comfortable putting one foot back for stability), back straight, and with your arms fully extended. The bar should not be touching your body.

Keeping your eyes facing forwards, elbows tucked in at your sides, and your body completely still, slowly curl the bar up.

Squeeze your forearmshard at the top of the movement, and then slowly lower it back to the starting position.

Repeat for desired reps.

Exercise Tips:

Your body should remain fixed and only your biceps and forearmsshould be used to move the weight.

Another mistake is not keeping the elbows fixed and in at the sides. You should not let your elbows come forward when moving the weight up.

And finally, you need to control the weight throughout the set. This means not letting it drop quickly!
