Form
Cues

- Full ROM — let elbows extend at the bottom
- Squeeze 1s at the top, lower 3s
Common mistakes
- Lifting elbows off the pad to cheat
- Half-reps from joint angle
Injury notes
Brutal at full stretch — drop weight if you have bicep tendinopathy.
Progression
Add 1–2.5kg when 10 strict reps land with full extension.
Indian gym reality
Machines vary wildly across Indian gyms — the same exercise on a different brand can feel completely different. Trust the movement pattern and target muscle, not the sticker on the machine.
If your gym doesn't have this equipment
- Use the free-weight version of the same pattern; the machine's guidance is convenience, not necessity.
- No bench? Two aerobic steps + a rolled towel works. For decline, prop the head-end on a lower step.
Home & hostel version
Chin-ups + resistance-band curls. Bands cost ₹300 and last a year.
Nutrition & recovery around this lift
Isolations recover fast — 24 hours is usually enough. You can hit the same muscle again the next day with a different exercise. For an Indian lifter, land 30–40g of protein within 90 minutes of finishing — 200g paneer, 4 whole eggs, 150g chicken, or a whey shake all work.
