Arms

Dumbbell Bicep Curl

The classic isolation lift for the front of the arms (biceps) — very effective with correct form, the kingdom of hidden cheats when wrong.

How to Do It

Stand tall. Feet shoulder-width apart, knees slightly bent, core braced.
Hold a dumbbell at each side. Palms facing the body (neutral grip / hammer hold).
Keep the working elbow pinned to the torso — it must not drift. No hip or back swing.
As you lift, slowly rotate the wrist outward (supination). At the top, palm faces the shoulder.
Squeeze for 1 sec at the top. Lower in control over 2-3 sec back to start. Full ROM is mandatory — no half curls.

Letting the elbow drift forward — the front delt takes the load, biceps disengages.
Swinging with the lower back or hips — biceps isn't really doing the work.
Half ROM (top half only) — hypertrophy signal cut in half.
Going too heavy — form breaks, joints take stress, gains drop.
Hyper-extending or hyper-flexing the wrist — wrist pain.

Start at 5-8 kg. 10-12 reps × 3 sets, form first. Add 0.5-1 kg per week.
Train alternating before simultaneous — more control. Doing both at once invites hip swing.
Watch elbow position in a mirror. The elbow shouldn't move.
Biceps 2× per week is enough — 48-hour gap. Pairs well with pull day (back).

How many reps should I do?

Hypertrophy: 8-12 × 3-4 sets. Endurance: 15-20. Strength: 4-6 (rare for biceps as an isolation lift).

Dumbbell vs barbell curl — which one?

Dumbbell: exposes side-to-side imbalances, fuller ROM, supination possible. Barbell: heavier load, harder for symmetry. Best programs rotate both.

Can I train biceps every day?

No. Biceps is a small muscle — needs 48-72 hours recovery. Daily training causes overuse, joint pain and a hypertrophy plateau.

The gold standard for back and arm strength — the compound movement many coaches would pick if forced to choose one.
