Grab an EZ bar or barbell with an overhand grip or underhand grip. You grip should be about shoulder-width apart. Slightly wider or narrower is fine.
Stand up with the barbell in front of your thighs.
Use your front deltoids to raise the bar out in front of you.
Raise the bar until it gets just above your head.
You can keep your arms completely straight, or your elbows slightly bent. For the underhand variation, I’d suggest maintaining a slight bend in your elbows throughout the exercise.
Once you’ve raised the bar, lower it back down.
Make sure you are controlling the weight on the way down and resisting gravity. Do not just let the bar drop.
