Biceps, Forearms
The classic biceps builder — a strict curl performed with a straight barbell, letting you overload the biceps with more weight than dumbbells typically allow.
How to do it
- Stand holding a barbell with an underhand grip, hands shoulder-width apart.
- Keep your elbows pinned to your sides throughout the movement.
- Curl the bar up toward your shoulders, squeezing your biceps at the top.
- Lower the bar back down under control to full arm extension.
- Avoid swinging your hips or leaning back to move the weight.
Coaching tips
- Keep your elbows fixed — letting them drift forward turns this into a shoulder exercise.
- A slight pause at the top of each rep increases biceps tension.
- Use a weight you can lift with strict form; swinging the bar reduces the muscle-building effect.
Common mistakes
- Using body momentum ("curling with the hips") instead of the biceps.
- Only completing a partial range of motion at the top.
Frequently asked questions
Should I use a straight or EZ bar for curls?
An EZ bar's angled grip is easier on the wrists; a straight bar allows a more natural supinated grip. Both build the biceps effectively.
