## How to do the Barbell Curl

1. Stand with your feet hip-width apart, holding a barbell with palms up.
2. Let the bar hang, elbows near your sides, and wrists straight.
3. Pull the bar up by bending your elbows, keeping your upper arms still.
4. Lift until your forearms are upright, then slowly lower it until your elbows are fully extended.
5. Repeat the movement, focusing on a smooth, controlled lift and lower.

### Full technique — 6 steps

1. Stand tall with feet about hip width apart, holding a barbell with an underhand grip.
2. Let the bar hang against your thighs with wrists straight and elbows close to your sides.
3. Set your ribs down and keep your torso upright without leaning back.
4. Curl the bar upward by bending your elbows while keeping your upper arms mostly fixed.
5. Raise the bar until your forearms are nearly vertical and your biceps fully shorten.
6. Lower the bar back to the start under control until your elbows are fully extended.

## Common mistakes

- Leaning back to start reps
- Letting elbows drift forward
- Bending wrists under the bar
- Cutting the bottom short
- Using hips to swing

## Form cues

- Keep upper arms still
- Curl through the pinkies
- Wrists stay straight
- Stand tall throughout

## How much to do

- **Strength**: 4–5 sets of 4–6 reps · rest 2 min · 1–2 reps in reserve · lower 2 s, lift 1 s
- **Muscle growth** (best fit): 3–4 sets of 8–12 reps · rest 1 min 15 s · 2–3 reps in reserve · lower 2 s, lift 2 s
- **Endurance** (good fit): 2–3 sets of 15–20 reps · rest 45 s · 3–4 reps in reserve · lower 2 s, lift 2 s

Reps in reserve: how many more you could still do when you end the set.
