How to perform Spell Caster
- Hold a dumbbell in each hand with a pronated grip. Your feet should be wide with your hips and knees extended. This will be your starting position.
- Begin the movement by pulling both of the dumbbells to one side next to your hip, rotating your torso.
- Keeping your arms straight and the dumbbells parallel to the ground, rotate your torso to swing the weights to your opposite side.
- Continue alternating, rotating from one side to the other until the set is complete.
Muscles worked
- Core (primary): braces the trunk and resists twisting to protect the spine.
- Glutes (secondary): extends and stabilises the hip — the engine behind hinges, squats and sprints.
- Shoulders (secondary): raises and rotates the arms and drives everything overhead.
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
- Brace as if about to take a light punch and breathe shallowly — don't hold your breath for the whole set.
- Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
- 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
- Cranking with the hip flexors or neck instead of moving from the trunk.
- Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
- Chasing weight jumps before the current load feels solid on every rep.
