ダンベルジャンピングジャック

A cardio movement that combines jumping jacks with dumbbells to work the shoulders, traps, legs, and core.

Instructions:

• Stand upright holding a dumbbell in each hand by your sides.

• Jump your feet out to the sides while raising the dumbbells overhead in a smooth motion.

• Jump your feet back together while lowering the dumbbells to the starting position.

• Keep your core engaged and your movements controlled.

• Repeat at a steady pace.

Common mistakes:

• Letting the arms swing loosely instead of controlling the motion.

• Using weights that are too heavy.

• Landing heavily without absorbing the impact through the legs.
