Lunges are defintiel a lower body exercise, but holding a weight overhead turns this into an arm workout.
- Stand with your feet hip distance apart. Hold the plate (or ball or dumbbells) overhead, locking out your arms and engageing your core.
- Keeping your belly tight, take a step forward with your right foot, coming into a lunge with both knees at 90-degree angles. Gently tap your left knee to the floor.
- Immediately step your left foot forward, coming into a lunge, gently touching your right knee to the floor.
- This counts as one rep.
