A traditional lunge, but holding dumbbells to help you build muscle.
1. As you press both dumbbells up, breathe out until the end of the movement, which is when both dumbbells are above your head, with elbows slightly bent.
1. Extend your arms fully and raise the dumbbell over your head, keeping palms to face upward. That is the start position.
1. Keeping your back in a neutral position and left knee soft, drive your elbow up, lift it to your torso, and lower back down to the start.
