[Standing Dumbbell Curl] mainly exercises the biceps.
The movements are divided into two types: alternating one arm and simultaneous arms. Keep your body upright, lengthen your spine, drop your shoulders, and tighten your core.
Hold the dumbbells with both hands, with your arms naturally perpendicular to your sides.
As you exhale, curl your arms with your palms facing you, inhale, lower them, and repeat.
Ideal number of sets: Do 4 to 6 sets every other day, 12 to 16 times per set.
