Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the upper arm still and pinned to your side so the movement happens only at the elbow.
- Keep tension on the cable through the whole range — pause before the stack touches down instead of letting it crash.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Swinging the torso to fling the weight up instead of actually curling it.
- Letting the stack yank the working muscle back at the end of each rep.
- Chasing weight jumps before the current load feels solid on every rep.
