How to Spell Caster
- 1
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.
- 2
Begin the movement by pulling both of the dumbbells to one side next to your hip, rotating your torso.
- 3
Keeping your arms straight and the dumbbells parallel to the ground, rotate your torso to swing the weights to your opposite side.
- 4
Continue alternating, rotating from one side to the other until the set is complete.
Common Mistakes
- • Brace your core before initiating the movement — maintain tension throughout the entire range of motion.
- • Control the eccentric (lowering) phase for at least 2 seconds to maximize muscle fiber recruitment.
- • Start with your weaker side first — match the reps on your stronger side to prevent imbalances.
- • Squeeze at peak contraction for a full second — this is where most of the growth stimulus occurs.
